    Did the job.
    Had a bit of a problem with my pond and these along with a new filter/pump have really cleaned things up.

    This worked for my small 1m x2m pond.
    Great stuff, fish are still alive. I put 2 packets in as first dose, Cleared the blanket weed over the 10 days. I need to do it again now but lasted a good 10 weeks

    Golden Review Award: 2 From Our Usersdoes it work? yes
    Thank you Swell UK. What a superb product, only wish I had been aware of it before. After just using one tablet, I saw the difference in a couple of days. Miracle! I would sincerely recommend this product to any pond owner as having a professional cleaning uses so much of our precious water to refill. Brilliant!

    Great product.
    We have had some green water and blanket weed problems this year and also due to an accident were unable to use the pond vac we normally use so I bought this product to help us and I am very pleased with the result so far. I also used Cloverleaf Blanket Weed remover – but on different days – and then put the tablet into the pond water as described on the packet.

    We are now nearly back to clear water and the bottom of the pond is looking so much better. It is good value for money too as our pond is 4000 litres so I only need one tablet each week. I will be using this next year from spring onwards to keep everything looking good.

    Golden Review Award: 2 From Our UsersBrilliant for cloudy sludgy ponds..I can see my fish again .
    After my yearly clean my pond was understandably cloudy put a full packet into my filter and less than 24hrs the water was crystal clear I’m very impressed I’ve used similar products but never had such a great result.

    It does what it says on packaging.
    The pond was given a good clean and we wanted to maintain the clean water and it was nice to see the fish again.

    Worked better than expected!
    The UV bulb in my pond filter kept tripping the electrics (even after replacing it). After a
    Few weeks, the water was so green I couldn’t see my fish! I needed something to clean up the pond water rather than replace the whole filter (we are moving soon and will be starting again with a new pond). So, I bought this, with some skepticism, willing to try anything other than wiring in a new filter. I placed one of the pouches inside the filter and left it. At first, nothing happened – still couldn’t see the fish and thought it was useless. After two weeks though, the water started to clear. I placed another pouch in the filter at this point and the water is now as clear as it was with the UV light working!

    Customer service are really good but the product is fantastic

    Well done for being out a organic product which works! And thank you for all the help on how to use it in such big ponds

    Amazing!!
    Holy fish paste, these things are incredible!! Use one every few months or so, just chuck it in a quiet corner of the pond and the next day the whole lot is crystal clear! Can really see the leaves at the bottom now great product will come back for more!

    Golden Review Award: 3 From Our UsersWorks eventually
    At first no improvement, but then added a second dose and two days later like magic the water is clear. I’ve actually got more fish than I remember now I can see them!!

    Clear water.
    I put one tablet actually in the pump and it appears to have kept the water very clear. My pond is only about 100 gallons so one tablet would probably work for about four weeks.

    Working slowly
    Easy to use, slow to see results but the blanket weed has reduced and I think it will just take time .

    cleared water in 3 days
    Left with pond after a death in the family. Pond was always clear until we got it and had no idea what to do. We just knew that the owner used to throw some tablets into the water and these were the only ones we could find on the internet. They worked like a dream.

    5.0 out of 5 stars Very impressive
    Keeps my Koi pond crystal clear, but I tend to have to use more tablets and more frequently than stated.

    Dropped one in our pond and after a couple of hours you could see through the water.
