Ecofix Sludge Destroyer/Water Clarifier, Safe For Pets, 473 Ml

Works really well, may be not as effective as the Fluval product a bit cheaper on the day.

Excellent. I used this regularly together with barley Straw extract from Pond Doctor and my pond is crystal clear without any harm to all the wildlife.

Algae slowing down, after putting 1st lot in, will see later as time goes on.

I was away during the autumn last year and my pond suffered from a surfeit of leaves. I removed as many as possible without disturbing pond life (newts and frogs). There was still lots of dirt gathered in the pond. This is not a quick fix. I have been treating the pond for about 6 weeks and now it has begun to clear. I will continue for a little while longer just until the aerating plants have grown somewhat. If you are patient it does work.

There was a lot of old debris on the bottom of the pond from years of neglect. This really seemed to help break it down and clear the water. It's not 100% gone but I wasn't expecting it to be. After a certain point if neglect, products like this help but it's impossible to completely remove it without draining the pond and using a specialized vacuum.

Excellent product clears sludge

Have four gold fish and this product has kept them safe in the pond while helping to break down some heavy sludge build up we had! Do recommend this product.

product does what it`s supposed to do.

Not a miracle worker but definitely helps clear outside pond water and decrease the sludge. I think adding catfish would help more.
