    Put it in and 24hrs later it was crystal clear. (I was suffering from fine dirt particles creating murky water)

    This product is definitely something you should have at hand for new pond builds.
    My pond is concrete and render finish, looks great but sends your PH value through the roof!
    This product equalises your pond to safe levels, and does it rapidly without harming your fish.
    I had to put the fish back in the pond almost immediately which resulted in 3 casualties, but gradually filled it to now final leve whilst gradually dosing with this product, fish have been spawning the whole time I’ve been topping the pond up and the PH has stayed within safe limits.
    Can’t rate this product enough

    Upon first use, my pond levels equalised so I guess this works. It could do with a measuring scoop but apart from that, it’s great.

    This is an excellent product if you want a crystal clear pond. It does take a few weeks to work, but in conjunction with an solar aerator it transformed my pond when many other products had no effect whatsoever.

    I was losing my big koi at 2-3 a day. The pond water tested ok except hardness (we live in a very hard water area) but was thick with sediment. I put 2 bags in, as my pond is nearly 10,000 gallons and only lost one fish the following day, then none in3 weeks. Water looks much clearer, but still a long way to go. This is not cheap but seems to be working.

    It does exactly what it says in the instructions. However, in my case the pond took longer to clear than some other commenters. Our 2,500 litre pond lost the bio-film almost overnight, but took nearly 3 weeks to “clear” and even then it was not crystal clear. A small complaint for a healthy pond. Our pond is full of healthy plants and wildlife.

    My PH in my pond has become an issue, I did try a blagdon product but it didnt work. My PH today was 6.4 on 20th April 2021. I watched the video on YouTube on how to use the product, I treated my pond and left it one hour. Incredible, we have gone from 6.4 to 7.2 – 7.6. I am really pleased and will retreat my pond in four months time.

    Very easy to use – just mix up the right quantity of the powder with the correct amount of water in a watering can and then apply evenly across the top of your pond using a sprinkler attachment. Initially looks cloudy but them quickly dissolves away to leave a clear and healthy pond. No problems whatsoever using it with our fish.

    Used to buffer approx 2000 litre garden pond with high pH (9).
    Dead simple to use, just sprinkle over surface (instructions state do not pre-mix with water). Worked pretty much overnight. Now almost a month since adding to pond, pH stable around 7.2, General hardness 125 (was zero before addition, so assume this is the buffer salts), Carbonate hardness at 50 (no real change). Pond is looking much healthier since adding this and filter bacteria.

    We have only just started our pond, and we were concerned about the water turning green and smelly in due course. So we bought this product, weighed the amount we needed for our tiny pond, and followed the instructions.

    Overall very happy!

    I ordered this because I had already purchased the pond clear from this supplier. As stated the pond clear is more effective after use of the pond equaliser. It’s a slow process because my poor neglected pond was in a bit of a state. The best thing is both products are natural so none of the creatures in my wildlife pond will be harmed by them. I will ensure that my pond is now kept in good order by using products from this supplier when needed.

    Golden Review Award: 7 From Our UsersAfter doing some research I found that all I required for the general good health of my garden pond was to buy a water ttreament. And then consequently fix my bind weed issue. The green algie is not so important ,at least for me, due to it only gets occasional direct light. However, this product covers both these aspcts very well.
    The information leaflet and follow up email,from the supplier proved important information for me. So, I can safely say that my pond is balanced, and of course treated. Nice…!

I had no expectations of any real improvement but boy I was wrong. I followed the very clear and simple instructions and WOW within 3 days I had crystal clear water and within a week, the green slime that I have spent a fortune trying to remove had gone!! My plants are no longer coated in the slime, the fish are looking great and the bottom of the pond is visible. Great product and great value for money.

    Very happy with this, along with the Extra pond clear the pond has gone from a green water pond, to a crystal clear pond.
    This was caused by cleaning out long over due filter cleaning, the pond overnight went from relatively clear to green water, also not helped by a failed clarifier. So after replacing the clarifier bulb, and even adding a second clarifier 2 weeks and very little change in the water. Adding the above 2 products and literally in a few days crystal clear water.. I’m very happy and impressed. Will continue to use Envil products as genuinely do their job. A satisfied customer for sure.
    The fish are happy too!!!

    I bought this product along with the winter treatment because the fish pond (approx. 11,000 litre volume) had been cloudy for some time even with numerous filter cleans and other pond clear products. I followed the Envii instructions, cleaning the filter, turning off the UV lights before adding one equaliser packet (750 g) and a double dose of winter treatment. That was 10 days ago and the water clarity has significantly improved. Very happy with both products.

He lost interest when he could no longer see the fish or keep it clean without wading in and scrubbing!!!! Having tried all sorts of potions and powders I tried this, I bought the normal strength and decided that just cleaning the filters was not enough so took apart all the box and cleaned everything….8 times…..each time double dosing. Not being a patient person I bought the Xtra Klear and after 2 double doses and thorough cleansing of the filters and pump and filter box….I have 15 fish including babies and lilies that I didn’t know I had so to any cynics and YES I am one and was up until 2 days ago, this stuff really does work

    Golden Review Award: 32 From Our UsersI guess like many others I read review after review about these type of products. My pond is not massive but I try to keep it clean and healthy. Over the past week or so I noticed that there was a white foam appearing on the surface of the pond. I searched the internet and discovered that it was probably due to too many nutrients in the pond, possibly caused by overfeeding and the water content needed balancing. Following more investigation I went for Envii Pond Equaliser. The fish were put on an immediate diet and when the product arrived I followed the instructions to the letter. Now 3 days later the pond is clear – the was a bit of clouding in the water – but that has now gone. I have to admit and this may be of help to others I did initially lift of the foam using a fish net and this may have helped I do not know. However the pond is now nice and clear and the fish have forgiven me for their enforced diet!!!
    An excellent product, easy to apply and I would recommend.

    Having waited patiently for a large bale of barley straw to do its stuff without successs after six weeks I am optimistic that, if I follow the instructions and dose regularly, I am optimistic that this Envii stuff will do what it claims to do within a week or so now

    Golden Review Award: 8 From Our UsersI am very impressed by how quickly this worked. So easy to use – just sprinkle it on the surface. By the next day the water looked better and I used a test strip to check for water quality and it was in the OK range for all the parameters (pH, GH, nitrate, nitrate, etc.). Our pond is now looking healthy with nice clean water. This is the best it has looked for a long time. I also use the other products from Bio8 – Sludge Klear and the one to remove blanket weed and Pond Klear and they all work very well. I am so pleased we have found this company and their range of excellent products. Also this company goes the extra mile in customer service. I contacted them for advice a few times and received a fast reply with good clear instructions.

    Golden Review Award: 18 From Our UsersIts quick to use,its powder and is easy to sprinkle on the pond, I just sprinkled over all the pond to help keep a healthy pond,as I cannot use my pond pump as there is frog spawn and it was awkward as it got into pump,so I got the frog spawn out of pump and placed it back into my pond,so to maintain my pond this was the best thing I could think of apart from the air pump that is putting oxygen into the water for all the creatures.

    Golden Review Award: 2 From Our Users2 weeks in and well impressed with the results so far. My koi are much more energetic and water clarity is significantly improved, filters got very dirty within a week so flushed them through as you would, but suggests it’s doing the job. Will see how things progress but so far am very impressed
