API Pond-Zyme Sludge Destroyer Pond Water Cleaner with Barley, Safe for Pets, 227 G Container

This product just did not deliver what it promised i.e. a clean pond. It is totally ineffective and waste of money. All claims made for the product are false. Extremely unhappy and feel cheated of my money. Would never buy it ever again.

Very happy with this exceptionally easy to use product. Very happy that pond is starting to look better

I have a small outdoor pond with frogs living in there. The water was dirty and smelly. I tried a few natural things without chemicals but nothing worked until I used this. Now after a couple of weeks I can see the bottom of the pond and the smell has gone.

Works good...

Many think anything should clear away green algae with a spoonful of something. Well provided you are maintaining your filters and do a partial water change, this stuff works great. I find it better as a preventative at 1st sign of build up.

I was not expecting such dramatic results. I have a small backyard pond with 6 large goldfish. It’s in the shade under a tree, but still grows a lot of string algae in the winter. Because of the fish and the debris from the tree, the water was getting very dark and full of sludge. I thought I would have to do a complete drain and scrub it out soon. But I found this product on Amazon with good reviews and decided to give it a try. I dosed the pond with a half dose (because I’m cautious with introducing new things to my aquatic environment) on a Saturday morning before heading out of town for the weekend. When I got home the next day, I was shocked! I could see the bottom of the pond everywhere in the pond. I could see the pond snails I added to take care of the algae. I hadn’t seen them since I put them in. I thought they had died. I even saw a tadpole swim by that I had NO idea was in there. If your pond needs help, give it a try. You will not be disappointed.
