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!

Not clearing water at all
I am sorry to say that I have waited for the water to clear after putting a whole packet in the water 6 satches waited two weeks still nothing and I paid £14 .99 , I don’t mind spending and having good results, I don’t like to complain but was looking forward to the water clearing. I have gone back to useing Tetra pond AlgoRem clearing green water which is a lot better.

Does work with a uv and patience
Very easy to use, my fault the water went green originally, but it has kick started the way to clean water again. But you do need a uv to keep it clear

Peu de résultats.
Après deux utilisation à double dose dans mon bassin à poissons (et plantes aquatiques), je ne vois pas trop de changements...
