FZONE 4L Aquarium CO2 Generator System Carbon Dioxide Reactor Kit with Regulator and Needle Valve for 600-800g Raw Material
INSTRUCTIONS
- Mix 600-800 gram citric acid and 600-800 gram sodium bicarbonate inside the bottle
- Add 900-1200ml tap water to the bottle and cap the bottle with the enclosed regulator quickly
- While the CO2 gas is produced slowly inside the bottle, adjust the needle valve accordingly. It takes approximately 45 minutes for the bubbles to stabilize after each needle valve adjustment
- If the solenoid is purchased, remove the bubble counter from the regulator (do NOT unscrew the regulator) and attach the solenoid to it. Connect the power cord to the electrical outlet. As gas is continued to generate inside the bottle, adjust the needle valve to the desired bubble count
Q: Is the bottle body strong enough under the pressure? What are the specific parameters?
A: Yes. The bottle is completely safe. The bottle has a safety valve built-in. It will open automatically when the inside pressure exceeds the threshold
Ideal DIY aquatic co2 system with profesional co2 tubing ,glass diffuser
CO2 generator is based on the principle reaction of citric acid and sodium bicarbonate mix with water, high purity of carbon dioxide gas is produced. After fully reaction, the CO2 goes through a pressure regulator, bubble counter and diffuser, provide a stable output pressure and flowrate, supply CO2 for photosynthesis, completely solve the disadvantages of the reactive generator pressure instability.
Fzone‘s CO2 generator kits included almost all stuffes needed in auqatic co2 system.
- 8ft professional PU tubing(NOT normal silica gel material) with fixing suction cups, super clear.
- glass diffuser with U shape connector.
- funnel and measuring cup make it easy for you to replace the raw materials
Dual gauge regulator together with safety valve, bubble counter
- Precision needle valve. The CO2 flowrate allowing to go as slow as 1 bubble per 5 seconds with our high precision needle valve.
- Safety valve, will open automatically when the pressure is higher than the allowed threshold.
- Bubble Counter, you can read your CO2 flow rate directly on the bubble counter cylinder. Bubble counter with check valve built-in to stop water from back-flowing to CO2 tank.
- Pressure indicator, indicates when it’s time to refill raw materials.
OTS Mini DC 12V Solenoid Valve
â—OTS 12V DC mini solenoid valve, safer than AC solenoid.
â— Energy-saving – low power consumption: 0.4 watt only. keeps the solenoid cool to the touch during operation.
â— Use with a timer, solenoid valve allows for CO2 to be switched on/off at defined times, e.g. to synchronize with the aquarium lighting.
â— Red LED on/off indicator – the operation (on / off) of the solenoid valve can be confirmed by the red LED.
â— No noise – without buzzing or humming sound.
â— High-quality model – OST brand, special structure for long-lasting durability and dependability.
Upgraded bottle height and diameter rate, solid material used
- Bottle height upgraded to 16inch (2inch higher than the 2L generator bottle), avoiding the overflow efficiently before the regulator screw in which is caused by the reactor of the citric acid and sodium bicarbonate.

Assembling the system was not difficult at all, looking forward to see how long it will last. So far so good
This thing was a game changer for me. I was previously attempting to use a yeast/sugar system that was messy and unreliable. It got me by, but this thing has been better than I imagined. I recommend getting the solenoid as well. It has cut my aquarium maintenance in half. My plants are very happy and my tank is looking great. I just followed the instructions. I’ve been using it for over a month now with no problems at all. I recommend you use care when putting it together.. no need to screw things in super tight. If you’re gentle and careful like I was I don’t think you should have any issues.
Llevo en acuarios muchos aos, tuve co2 echos con un extintor, con una botella de plstico y cuentas gotas hospitalarios y sistemas que me costaron mas de 300e de marcas muy conocidas en acuariofilia.
Esto es impresionante, su funcionalidad, su equipamiento, lo limpio que es, lo bien que funciona, todo muy bien empaquetado y elementos de buena calidad.
Me sorprendio su manmetro, su llave reguladora y la botella, realmente se ven slidos y funcionan sin problemas.
Muy muy recomendable y fcil de usar. Me sorprendi muchsimo y lo recomend al 100 %.
Not a lot of instructions on how to set it all up. I had to search a lot of steps to make sure I was setting it up right. Once running it is working great.
The system leaked and solenoid was apparently to blame. Company replaced solenoid and all seems to be working well now. Great customer service.
Works well but need to change the little diffuser that comes with it. One fill-up lasts about 4 weeks with 2-3 bubbles a second runny for 8 hours daily.
Make your own co2 with citric acid and baking soda, what’s not to love. Plants are thriving.
On the positive side:
1) Setup was pretty straightforward, though printed instructions are a bit fuzzy. I used a couple of semi-helpful YouTube videos and online basic chemistry tutorials for assistance.
2) A single charge (recommended mixture of citric acid and baking soda) has lasted four weeks (and still going), with a rate of one CO2 bubble per second for most of that time.
3) Though a drop checker suggests a suboptimal CO2 level, what’s being produced has noticeably enhanced plant growth and health (upping the CO2 release rate may make a bigger difference).
Negatives:
1) The CO2 diffuser disk provided with the kit is smaller than others sold separately, and released a number of larger bubbles, thus limiting surface area for diffusion through the tank. I obtained a larger disk from Ciscea that is efficient at producing a wider stream of microbubbles in the aquarium.
2) The needle valve on the FZone apparatus is _ very_ sensitive, so it’s tricky getting the exact bubble rate you want.
Overall, I’m pleased with how the setup is working thus far.
Le bombole ricaricate sotto pressione durano circa 6 mesi.
Sar pi preciso in futuro sulla reale durata della carica ottenuta col metodo di produzione e sul relativo costo.
Ich besitze ein 200 Liter Aqua, welches noch bis vor einem halben Jahr mit Flaschen 2,5 kg versorgt wurde.
Mit dieser Flasche kam ich ca. 3 Monate hin und 25mg pro Liter Co2 zu haben.
Da die Fllungen immer komplizierter (Hndler) und teurer werden und bei dem Spritpreis jede Fahrt mit einberechnet werden sollte, stellte sich mir irgendwann die Frage: und nun?
Nach vielem Lesen in Foren ber BIO-Co2 (BIO BIO ich kanns nicht mehr hren) etc. und vergleichen von Angeboten bin ich hier bei dieser Flasche hngen geblieben und sehr sehr glcklich damit.
Warum?
Weil diese Flasche mit einfachen Haushaltsmittelchen die “fast” jeder Zuhause hat befllt wird und “IMMER” verfgbar ist sollte etwas mal Leer sein.
Ein weiteres wichtiges Kriterium war die Sicherheit welche mir bei BIO-Co2 und diversen Konstruktionen nicht gegeben ist.
Ich hab nicht so gerne irgendwelche explodierende Flaschen in der Wohnung, schon gar keinen BIOgasanlagen Geruch. Hab ich aufm WC….langt :-).
Wie lang komme ich also hin bei 200 Liter und 25mg Co2?
Wasserwerte sind KH 5 bei uns.
Bis jetzt mit 200g Citronensure, 200g Natron und 300ml Wasser ca. 4 Wochen und noch nicht Leer, neigt sich aber langsam dem Ende entgegen.
Man kann die Flasche, da sie strker in der Wandung ist als andere, auch mit 400mg Zitronensure und 400mg Natron + 600ml Wasser befllen. Macht dann denk ich mal 8-10 Wochen Co2 fr einen Preis der mehr als nen Preisschlager ist. Muss aber nicht unbedingt sein mit den 400mg.
Fazit: Rundum glcklich und zufrieden. Alles dabei was man braucht. Guter Hndler
Tipp:
Schmiert bitte smtliche Dichtungsringe und Gewinde vor Gebrauch mit Melkfett oder Silikon ein, zwecks der Schmierfhigkeit smtlicher Teile. Dann geht die Flasche auch wieder auf wenn sie Leer ist :-).
la cercavo da tempo, ma ho aspettato un mese per fare la recensione.
addio bombole usa e getta che nell’ultimo periodo faticavo a smaltire… (non le ritiravano i negozi ne la piattaforma ecologica).
Dopo un mese a bolle variabili tra 3/5 secondi la bombola ancora nella fascia positiva di funzionamento.
la consiglio al 100%
I am new to CO2 in a high tech tank. This set up really works well. Have it on a timer and for my 10 gallon lasted a month. Moved it to my 30 and will need to tweak it but obviously running out faster. Setting time for a little less and will probably up the raw material just a little to stretch it out further.
Receive an open package, but I will let it go, the suction cup is useless, it can’t hole the tubing
However, the system works
2/9/2022 in a 5gallon, first batch only lasted 2 months.
Easy to setup and use. Took off one star due to the bad suction cups that come with the diffuser and the diffuser not diffusing at 100% surface area. CO2 bubbles come out only in a small area so I had to purchase better one. The 2 suction cups that are included with the CO2 line are much better than the 2 that came with the diffuser. Was concerned purchasing this after reading the bad reviews but I haven’t had any problems yet 2 weeks into using it on timers.
***Missing U item that hangs over rim of tank
Does the job as required even when running on 3 bubbles per second it lasts a week. Suggest bulk buying baking soda and citric acid as these will last best part of a year.
Pour la diffusion de CO2 dans votre aquarium qui vous prend seulement 200 g. de bicarbonate de soude et 200 g. d’acide citrique et 300 ml. d’eau il se dveloppe presque immdiatement le gaz ncessaire..vous avez a peine le temp de visser la valve et voila que vous verrez la pression monter ensuite raccorder une lectrovanne entre le diffuseur et la sortie qui vous permettra de couper la diffusion de Co2 la nuit (vendu sparment) mais qui est ncessaire car la nuit vos plantes rejette naturellement le Co2…alors OUI je suis installer depuis 24 h. sans regret entirement satisfait et c’est conomique car pas besoin de racheter de bouteille de CO2 par la suite..
Muy sencillo sistema para CO2 DIY, el tanque es de buena calidad, mucho mejor q hacer la mezcla en botellas de PET q no resisten la presio
Before buying I read this unit would produce CO2 for up to three months. I’m seeing only 4-5 weeks of CO2 generated. My bubble counter is set to 50-60 bubbles per minute.
Finde ich eine tolle Alternative zu klassischen CO2-Flaschen. Mit Billig-Systemen fr Bio-CO2 gar nicht vergleichbar. Hier bekommt man dank des Druckbehlters mit Manometer und Nadelventil ein recht professionelles und zudem kostengnstiges System. Hochwertig verarbeitet und pflegeleicht.
Der Mischvorgang und Dosierung ist recht einfach, nimmt bei mir ca. 15 Min in Anspruch, inkl. Reinigung der Flasche. Die Zutaten sind recht gnstig, wenn man sie in Gropackungen kauft. Bei mir hlt die Flasche ca. 1 Monat – 200 L Aquarium mit Zielwert 20 mg/L. Daher wrde ich das System eher fr kleinere Aquarien bis ca. 100 L empfehlen, dann sollte eine Fllung ca. 2 Monate halten, was schon recht bequeme Lsung ist.
Da quando ho comprato questo prodotto, mi sono completamente dimenticato di avere la co2.
I risultati sono ottimi e con il giusto diffusore, non quello in dotazione, va da dio.
Lo consiglio a tutti 2 mesi dalla prima carica e ancora pompa, giorno e notte
Just back into the hobby I used to dread my CO2 bottles running out and having to hope the seller was open for my refill. This canister is a breeze. So easy to set up, great in operation and with the optional solenoid it’s just a case of set it up and let it do it’s thing. Refills are a doddle and cheap too. Very pleased.
It does what is supposed to do, I also ordered the solenoid for a complete system!
Seems to be doing the job. The only problem I had with it was that the tubing is quite robust and is hard to straighten. So when you attach the diffuser and the cups to the tubing, it tends to turn to the side or come away from the glass. I resolved the problem by rolling the tubing the opposite way and adding more suction cups. Excellent value for money and the regulator is solid and not flimsy
Been using for a couple of months now – been working fine. Just put in the baking soda and citric plus water and in 5 minutes is producing C02 in my aquarium.
Muy buena calidad de los materiales incluye el cilindro, las mangueras y el difusor el cual recomiendo cambiar por uno de mejor desempeo
Funciona a las mil maravillas. Muy contento con la compra
No preciso dar as 24 horas para funcionar, passado 1 hora j est no verde e pronto a ser utilizado.
No meu aqurio estou a usar uma bolha de co2 de 4 em 4 segundos, e est a funcionar corretamente.
Was good price for that value and I buy this, for now its have second load of co2 and working well, for me its can be only add better quality hose and sucction cup because after month in tank its rock hard and not hold hard hose in place.
I have a before(bottom) and after(top) picture of only one month using this co2 kit(with none before). Its super simple, cheap to run with simple ingredients, and extremely effective for plant growth
Our first attempt at filling the tank didn’t work out, no fizz at all, but we believe that was due to our “user error” of pouring in the dry ingredients one on top of the other & not mixing them up first. 2nd attempt, we mixed & there was an immediate reaction. Easy to assemble. Works Great! Filled up 4 months ago on 30G tank & the tank is barely a 3rd down. The diffuser isn’t the fanciest but overall great for the price. The directions could be improved, very bad english translation, the internet helped.
Just a FYI, my video has a Neo diffuser instead of the included one. Other than that, the amount of flexibility and precision afforded by this DIY system is worth it alone. I feel better and better about this purchase because of the amount of money I’m saving from disposables!! It also helps that these are solid enough products! Remember: need to buy citric acid and baking soda separately!
I was new to co2 and this thing is amazing! My plants started to grow like crazy. I was struggling with plants for years. Anyone who is saying LOW tech, no co2 is sick in the head. Buy this co2 generator, but with solenoid!!! Without solenoid is useless.
A very good CO2 system from FZONE. The extra parts that came with the bundle are useful and overall great built quality (i.e. pressure valve, bubble counter, extra tubings, diffuser etc.). The head doesn’t leak and is very easy to screw tight. The taller bottle helps when filling up the bottle when adding the water. (gas/water don’t just bubble out). Will see about how durable this is in a long run (I’m on the 3rd week of using it).
This is an amazing Co2 solution for my planted 10gal. I love this setup.
Perfect way to get started with co2. Been using for almost a year now with zero hiccups.
First time setting up CO2 for a planted aquarium. This set up is easy and after proper research anyone can do it. Mine has worked perfectly for 3 weeks now and just replaced the materials. I really love how inexpensive the materials are and the reusable tank pays for itself. A little nerve wracking when you add the powders then the water, you’re in a race against time to get all the water in while it’s trying to bubble up and react. The kit comes with a funnel, but would recommend to order a larger mouthed one. Also have handy another measuring cup, one for powders and one for water. The safety of the canister is a big plus for me. Ensure all parts are tightened, test with soapy water to make sure there are no leaks. I keep the canister in a small bucket because it condensates and becomes very cold. All in all, this set up is affordable, durable, and perfect for my 29 gallon. Would recommend to anyone.
This has been incredibly instrumental in getting my tank to where it is now. I couldn’t recommend this more. And the customer service was quick to respond and help with the questions that I had. It’s cheap, efficient, and overall way better than having to go and get a refill every couple months. Had it for over a month now and it’s still on its first round.
My co2 generator arrived yesterday. I immediately set it up and it works as advertised. I don’t have an aquarium, I’m using it as a co2 source for a mosquito trap. The thought of lugging co2 tanks back and forth for refills didn’t appeal to me so I decided to try one of these. The co2 line for the trap fits perfectly to the output nozzle at the top of the bubble counter on the generator. I have it set to 10+ bps, higher than what you’d normally use for an aquarium but just good enough to lure the flying bloodsuckers to their demise. It’s been pumping out co2 for around 21 hours straight now and the pressure still looks good, bubbling away. Regardless of how long it ends up lasting on a single charge, it is a lot easier to refill this thing than lugging big co2 tanks back and forth.
Funciona perfectamente. El rendimiento es extraordinario sobretodo comparndolo con las botellas de plstico. Por poner una pega, la llave de aguja no es precisa, al menos al momento, puesto que hay que abrir y cerrar y esperar unos minugos a que se estabilice. Estoy con la primera recarga a la mitad de la cantidad recomendada, 100 gramos de cada producto, y lleva dos semanas y media a gota por 3 segundos, y sigue con la misma presin.
EDIT: the high pressure gauge is showing pressure now, I believe it is/was faulty as it took over 48 h to show any readings, the system was up and running with low pressure readings looking good all this time. The dial might have been just stuck in place initially.
Provides me with good, cheap CO2. Got the solenoid as well, all working pretty good so far.
Seems to be working but the item was delivered faulty. I’ve been wondering why it wasn’t showing any pressure building up, turns out it was but the high pressure gauge was not working, low pressure one seems fine.
Works great be gentle with the needle dial. I have been injecting Co2 via this into my canister filter out hose. Plants love it and it went about 3 weeks before I had to change the ingredients. Two big bags of citric acid and baking soda should last me a long long time.
Absolutely great item well worth the price in the long run as all you need is bicarbonate soda and citric acid would definitely recommend you buy the automatic solenoid kit with it as its less messing around
I did have a few issues at the start.
I had a leak at a valve not sure where and had to replace the contents twice over 3 days. I then bought a solenoid as there wasn’t an option to add with my purchase and an attachment nut again had some leaks – I’ve added additional washers, tightened the bolts and fingers crossed it’s been running for about 4 days and the content pressure clock has barely moved. I’m running a bubble a second.
The PSI for pressure leaving the generator doesn’t work at all and never has since I’ve set it up. I’m able to see movement only by the bubble counter. Not a biggy but would be nice to see this.
Packaging was good and nicely set out. I read some reviews about how bad the instructions were before buying so watched some YouTube videos which really helped. Also I didn’t think the instructions were too bad just that there was no way of identify what material was A or B – but another person sates this in their review.
On a whole for a novice just getting into CO2 systems it’s not been to bad considering the prices of some of the other generators. The product itself seems to be made well, just a shame about the psi pressure gage.
Hopefully I’ve fixed the leak and I’ll get more than a day out of the contents.
Dopo 10 giorni di utilizzo la bombola tiene perfettamente la pressione, ho tarato il riduttore a 1 bolla di CO2 ogni 2 secondi, sta funzionando da 10 giorni e la pressione non accenna a calare quindi vuol dire che la guarnizione del riduttore tiene, unica pecca uno dei 2 manometri non misura assolutamente niente ma nel complesso il prodotto funziona egregiamente.
After getting a dud from the other company that sells these, I took a risk and got another from FZONE. It works beautifully for my garden, got my PPMs up into the zones needed. Looking forward to continued use of this product.
Producto de calidad, compr el cido ctrico y bicarbonato aqu en Amazon y el efecto es inmediato, parece un equipo profesional, difusor pequeo ideal para acuarios pequeos, se puede regular a la perfeccin la cantidad de co2.
Was a skeptic.
It made a big difference in my 70 gallon tank.
I love the fact that you can refill without leaving your home. You will need to buy the solenoid separately to use it on a timer. It’s not necessary but comes in handy to have it shut on shut off at a specific time. Last about 3 weeks for me. Refilling is easy! Plants start growing within a week!
After adding this generator to my tank…. Plants started to pearling!!! And growing like crazy. I have to trim them every few days! This generator is very easy to use. For my little 100l tank it lasted one month. I am very happy. I added a solenoid and I have a perfect compact co2 injection system. Thank you !!!
Easy to use, just add the two ingredients, add water and screw the regulator on. The production of CO2 is instant. The pressure will be high enough after a couple of minutes to allow your to start feeding CO2 but will continue to rise to full pressure over several hours.
I think it looks smart.
No mess or smell unlike yeast/sugar.
Cons: the only thing I would moan about are the instructions are not well written (they have been translated from Chinese into English).
Things that stand out:
1. You have to add Citric Acid and Bicarbonate of Soda. The Instructions say add material A/ 200g and material B/ 220g but they don’t say which one is which. See below.
2. Instruction do not mention the filter or how to fit it.
3. Gauges on regulator are marked in PSI but instructions mention 1MPa(10KG/CM2)
4. Also, my regulator was faulty (see image) as the output pressure always showed 0psi. It still worked though.
Why 5 stars you may ask ?
Because their customer service was very good.
I told them about the faulty regulator and they sent me a new one from China (took about 2 weeks).
I mentioned about the instructions and was told they would look into it ASAP.
As for the weight of the ingredients here’s a quote from customer service:
“Please see the following steps:
1.Mix 200 gram citric acid and 220 gram sodium bicarbonate inside the bottle
2.Add 300ml tap water to the bottle and cap the bottle with the enclosed regulator quickly
3.While the CO2 gas is produced slowly inside the bottle, adjust the needle valve accordingly. It takes approximately 45 minutes for the bubbles to stabilize after each needle valve adjustment
4.If the solenoid is purchased, remove the bubble counter from the regulator (do NOT unscrew the regulator) and attach the solenoid to it. Connect the power cord to the electrical outlet. As gas is continued to generate inside the bottle, adjust the needle valve to the desired bubble count
Please feel free to contact us if you have any question or suggestion.”
I hope this helps someone else.
Awesome kit. Keeps a steady pressure for almost 2 mo with almost 2 bps and scheduled 8 hrs per day. Get the dc solenoid to add a time
It is working perfectly. I have ir on a solenoid and a timer.. Plants are already starting to perk up.
Great product, great seller, recieved my items to find out solenoid was damaged. Seller resolved issue immediately. Thanks again!
Product, good quality, and easy to use. Secondary pressure gauge isn’t working but it makes no difference to me, as I use the bubble counter as a primary dosage measurement. I use it on a 20 gallon planted aquarium. With 20 shrimp and a betta for livestock. And valisneria + dwarf hairgrass + scarlet temple. 1-2 bubbles per second makes my plants pearl, and fish seem fine as well. All hail photosynthesis 😀
I absolutely love this Co2 generator. I’m running mine at right around three bubbles a second in my thirty gallon heavily planted aquarium and I get three two four weeks per fill. I ended up buying a solenoid for it so it is now completely automated. I run mine eight hours a day and my plants look absolutely amazing. I’ve read some negative reviews on the regulator valve but must say I couldn’t be happier with the way mine has performed so far.
Works as expected. First solenoid was leaking but the seller promptly replaced and now it’s working great!!
DIY CO2 taken to another level, this uses a reaction of baking soda, citric acid, and water to create usable CO2 for aquariums. One can expect that a 2.5l tank will last around a month or longer depending on bubbles per second. Works well with a solenoid valve.
The customer support is very good. This was my first time using CO2 in my tank so I wasn’t entirely sure how many BPS to have set on my tank I found their contact on facebook and Once I messaged them they responded back within 5 minutes and quickly helped me have it up and running
Easy to set up and use i did not get the regulator works fine just have to manually turn on/off.
I’m so glad I found this CO2 kit! I am a beginner when it comes to using a CO2 system and all the parts you need was confusing for me to try and piece buy stuff. This has ALMOST everything you need to start… I knew I needed it to be on a timer along with my light and from the description, it does say I would need to purchase that separately (and it was not expensive – especially compared to companies that cater to the aquarium world and professional CO2 set ups), a solenoid and even suggested what to look for.
Very easy to put together! The sticker instructions needs to be reprinted in my opinion, to give the correct amount of the citric acid/ sodium bicarbonate (equal portions, btw…) to use. That is not clear AT ALL. I suspect that there may be kits out there that actually has the chemicals already included. This one does NOT. But no worries, the stuff is cheap to buy too. Oh, and if you don’t have a gram scale, get one of those too…
Would give it 5 stars overall except that the pressure gauge got stuck at 50psi. My CO2 gas was empty and needed to be changed and I thought I needed to wait until that pressure was zeroed out after releasing the residual gas pressure. Never did. I went ahead and opened it. No issues since my gas was gone after I opened the valve to release whatever was left. Even after opening, never went down. Did the remixing of the 2 chemicals, added the water, and reattached the pressure gauge thing (). All works well except that one gauge. I’m not worried since there is a safety pressure valve if pressure ever got too high, etc.
I’m addicted to my planted tank and I know I will get more tanks in the future. This is a way cheaper option to use CO2 than buying a refillable tank and going to the sporting good store to get it refilled!
I am using this great little C02 generator with the optional solenoid on my 29 gallon tank in conjunction with a Hygger 24/7 led light. I set the light to a 12 hour day where there is 6 hours of full spectrum, full power light surrounded by 3 hours of light at 20-30%. I have a timer on the C02 to be on at about 3bps when the tank is under the 6 hours of full lighting, and this schedule is working great for me. My plants are growing really well, the alternanthera reinecki is full, bushy and super red on both the top and bottom leaves, the amazon swords and java ferns are reproducing, and the vallisneria is sending up lots of new leaves. I am getting approximately 30 days per fill up at the 3bs, 6 hour a day setting, so it’s not a hassle to maintain at all. I highly recommend this product, especially if you don’t have anywhere nearby that can fill up a full size C02 tank!
I have been looking at CO2 units for my tank, but really didn’t want to deal with the disposable canisters. This fit every checkmark I had and it works perfectly.
I was very impressed with the craftsmanship and quality of this kit. I had CO2 in my tank minutes after mixing the solution. Spend the extra money and get the upgraded solenoid.
Works well. Only issue I have is that the tubing is a little hard to manage because it is so stiff and the u-shaped tube that came with it to go around the top of the tank is not wide enough for my rimmed tank.
Only had this running 2 days. Had a big hair algae problem. Made the water look fuzzy. Ran this over night then for 4 hours next day. On day 3 the water looked crystal clear and a lot of algae disapated! Plants are looking good. Algae should be cleared up in just a few more days.
La relacin calidad precio est bien, te permite ajustar la administracin de CO2 al acuario de forma precisa.
Very easy unit to set up, but the instructions could be a little more clear. It only references 200g of “Material A” and 220g of “Material B” without specifying which is which. Once I searched around and settled on citric acid as “A” and baking soda as “B”, I was able to have it up and producing CO2 within about 10 minutes. After doing “Coke bottle CO2” for years with sugar and yeast, this is a much cleaner, much nicer, much more adjustable way to do CO2 injection.
My only other complaint is that the included glass “U” will not fit over a standard rimmed aquarium. You need rimless or something less than 15mm thick. Oh well, I just left it out and hung the air hose over the back.
El sistema.funciona bien, la mezcla me dura unos 10 das aunque depende de la cantidad de burbujas que uno quiera. Estticamente esta bien. Yo le compr el sistema que permite que se apague de noche lo que permite ahorrar. Sin este sistema creo que hubiera durado una semana la mezcla. Es fcil su montaje y la mezcla se hace rpida. Los productos para la mezcla son asequibles y los encuentras en Amazon sin problemas.
This product works but it leaks it made me have to re do the whole reaction when you screw on the cap when the reaction happens DO not put the black ring around it makes it leak gas !! but besides that no problem.
Das Teil kommt gut verpackt.
Bitte sein Sie vorsichtig, wenn der Schlauch auf den Glasdiffusor kommt, da das Glas auch kaputt gehen kann.
Ansonsten funktioniert alles sehr gut.
Die Flasche wird unten eiskalt und oben warm, wenn die Reaktion einsetzt.
Erst sollte man das Natron und die Zitronensure einfllen, aber bitte nicht mischen. Dann den Behlter leicht kippen und Wasser zufgen. Dann schnell zuschrauben.
Das Gert ist wirklich gut und ich bin bislang zufrieden. Fr die drftige und nicht ausreichende Bedienungsanleitung gibt es einen Stern weniger.
Insbesondere gibt es am Filter (dem schwarzen Teil) an einem Ende so ein weies Ding. Es sah aus wie eine Art Kappe und ich hatte es schon fast entsorgt bis ich dann in einem Video in den weiten des Netzes sah, dass jemand dieses Teil drauf lie. Also wieder drauf damit und es klappt.
Das Verhltnis von Zitronensure und Natron funktioniert in einem Verhltnis von 1:1. In der Anleitung steht 220g und 200g ohne einen Hinweis, ob mehr Sure oder mehr Natron gemeint ist.
Der Blasenzhler muss mit Wasser gefllt werden. Er sollte nicht ganz voll sein. Ich habe dazu eine Spritze genutzt. Es geht aber auch, in dem man das Teil aufschraubt…. Habe ich natrlich erst hinterher bemerkt.
Ich kann diesen CO2-Generator empfehlen. Sollte ich noch weitere bentigen wrde ich wieder darauf zurckgreifen.
This has been a fantastic do it yourself system. I’ve had it a little over a month now for my 45 gallon tank and have only had to refill it once. I do equal weight of 200g each and 300ML of water, from my research it appears to be a 1:1 ratio on CO2 output. Not that much of a difference, but you’re just wasting a little bit of product.
I only deducted one star because the CO2 diffuser could use an upgrade. I started to believe I was wasting CO2 because it didn’t appear to be dissolving enough to the point where my CO2 indicator said it was good. I purchased another diffuser on Amazon here: https://www.amazon.com/gp/product/B0779QXBZJ/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1 and it has been fantastic, and I’ve actually been able to lower the bubble count because it diffuses it so well. The system is now perfect. I also did purchase the additional Solenoid and have had no issues with that.
I will update my review if anything changes 🙂
Well made and easy to use. Very happy with this purchase! Got this so I didn’t have to leave the house for Co2 tank refills.
Nun ich muss sagen,funktioniert besser wie die anderen Marken Produkte.
Seems quite sturdy and works very well. instructions are not very good. For example, it says 200g of substance A and 220g of substance B. Only problem is it doesn’t say which substance is A and which is B. I just putt 200g of each and it is working fine.
Used the 2 bottle system very messy
This makes the process so simple
Not cheap but is worth every penny
And looks good too
Star categories are all irrelevant but the tank and valve assembly function perfectly for about 2 months now. Definitely recommend especially after having a 2 liter explode in cabine
Does what I need it to do. My plants are breathing better already!
Initial order came with broken regulator, leaked at the power input. Company replaced without question promptly, and this thing works well for agricultural purposes.
I love this CO2 generator! I have multiple low tech planted tanks and wanted to dive into the world of high tech gear. This unit is an all-in-one. The steel canister, tubing, regulator, bubble counter, diffuser are all included; even comes with a plastic beaker and funnel for adding dry mixing agents. The only extra thing you will need to buy is the DC powered solenoid and a timer to fully automate the system and of course the mixing agents. Carbon dioxide made easy with the extra incentive of not needing to go find a place to exchange your tank when you are out of CO2.
The design the sleek and modern and not tacky like when using 2l soda bottles.
The built is solid and I can tell this is built to last.
It does take few hours for the bottle to built up enough pressure when first setting up but no leaks and is working as intended.
Plants are responding well and pearling. Will definitely be getting my co2 equipment from fZone for future builts.
Pros:
* Solid aluminum cylinder with safety valve that is designed to open if the pressure builds up too high
* The pressure gauge fits snug
* Should have bought the one with solenoid valve, thought I could already use another one I had but that is not actually safer for this tank is what I figured
Improvements :
The instructions could be a little more clearly written but some research beforehand should be good enough.
Could be better if they can combine the one with the solenoid valve as a single product without having to buy separate
Helps plants grow. Puts bubbles in the water. It was for the fish tank. Good value compared to other sellers. Instructions not super clear. But if you read into it, alot, then you can figure it out probably.
my needle valve stops working after about 3 hours, psi is stable and installed correctly.
if I push on the needle valve bubbles stop coming out if I gently pull on the needle valve enough bubbles to gas and kill fish in a 100 gallon come out. I’m not sure why it stops producing co2 atleast it’s not slowly adding more bubbles over the 3 hours, ordered a new needle valve from somewhere else hopefully it fits correctly
I ended up googling the citric acid/baking soda ratio and it seems to be a 1:1 reaction. I understand that it may be difficult to change the included instructions, however it should at least state in the amazon listing that the instructions included are incorrect. If you use the included instructions it’s not the biggest deal, you will just be wasting 20g of whichever material you use 220g of.
So far so good. The package arrived neatly arranged and all items that were meant to be delivered arrived in great condition. I posted a question as to whether or not I can use a splitter and add another solenoid bubble counter to supply CO2 to (2) nano tanks. I will post updates after setting up the tank and start to use the generator. My initial impression is that I am quite happy with the product as delivered
I bought this just to test it out. I was skeptical if this would work but it does! I have had this set up for a day and I already have plants pearling!
I also put 1 cup baking soda, citric acid & 1 1/3 cups water and the pressure the tank is full!
Very pleased. I debated for a little while if to buy this product or the whole regulator, co2 canister etc… due to cost I chose this generator but even tho it was the cheaper option I feel I made the right choice. Quality is solid. Holds pressure well and does not fluctuate. No leakage at all as of day 3. I chose the non solenoid because I thought it would be the piece that would fail or leak. If I could go back I’d choose that option. All in all I’m very please with my purchase. Shipping was fast and arrived the 2 days a head of giving date which is another plus.
I want to add. … The customer service was fantastic. The product I purchased 9 months ago had an older version regulator and I noticed the psi wasn’t getting above 5. When I investigated it, using soap and water, I realized that I had a small but significant leak along the seal (hence the red tape). I contacted their customer service through Amazon and they responded within 2 days. After sending them a photo, they immediately offered to send me a replacement regulator, for free and no questions asked. I couldn’t have asked for better customer support.
This is awesome. I love it and love how easy it setup. I’ll be definitely buying another one for my other tank.
Quality build
Solenoid is a must if you need to use a timer which you can buy separate.
Great alternate to a CO2 tank for a nano
Should last at least a month per charge if you use it 8 hours a day and around 1-2 bps
Funnel and measuring cup included. Citric acid powder and baking soda are required[inexpensive]
Instructions shows illustration on how to start. Bottles has instructions too.
I also use a Fzone regulator for my other CO2 setup. Highly recommended. 5 stars
