1 litre

This product certainly works. I have a small pond which wasn’t at all clear and within a few days after application the pond cleared quite significantly.

Works very effectively. Had brown opaque water, high volume UV filter running, added other chemicals but this was the only one that made a significant difference in a few hours. The fish seem ok and its nice to see them again. My only gripe is that its expensive for the amount you get. Using less than the recommmended amount I still used half the bottle on initial application for a modest pond.

Used this product. Killed the algae but took a long time for it to clear....weeks. Not sure if it actually worked for that as I also used another product too. But definitely killed the algae.

This will clear your water, but it does take a few days to work.It does not however do anything other than that. It will not clear algae or pondweed.

I only have a small nature pond which looked dirty and pea soup green. I bought this product to hopefully try and clear it. It only holds 110 litres so I measured the correct amount, 5ml, mixed it with water and poured it in. Nothing happened for about a week then slowly it started to clear and by the end of the second week it is crystal clear. The bottle is 250 ml which is obviously enough to treat it 50 times ( should it need it).So, a great product at a good price.

I have a very small (50 gallons) new pond. After putting some plants in, the water was slightly cloudy, from the soil I guess.I carefully measured the required amount of solution and poured it into the pond - BIG MISTAKE!!! HUGE!IMMEDIATLY EVERYTHING GOT WORSE, my little pond looked SO much worse, it looked like ducks had been paddling in it!This was on July 5th, and its getting worse by the day.I REALLY regret putting this into my pond.I paid £12.49 to ruin my new pond, so angry.Returning for a refund.

Pond was crystal. Not sure how long it took but pond has never been so clear within 1 week after use.

Item arrived quickly and worked well clearing my pond

The product itself is good! But I have ordered the Blagdon Green Away twice, and the seller has replaced my order with the Clear Pond, with no explanation. Guess I can't trust the seller! Beware.

2 traitements et aucune amélioration ! C'est agaçant toutes ces belles promesses n'ont tenu. Encore de l'argent jeté par les fenêtres.

No fue muy buena compra, no se si por no saber exactamente cuanta cantidad poner al estanke tengo o si tenia espectativas mayores que no cumplio, tuve que utilizar otro producto para conseguir algun resultado y ver el agua clara, seguramente agruparia las particulas y realizó su funcion, pero yo esperaba fuera otra su funció, fuera UTIL limpiando el alga,,,

Dieses Produkt hatte Null Wirkung ,das Wasser ist genau so trüb geblieben wie vorher.Außerdem wäre eine deutsche Gebrauchsanweisung,wie man bei anderen Artikeln kennt empfehlenswert.
