UltraClear Oxy Pond Cleaner, 8lb

I have goldfish in my pond and I'm able to use this quite liberally without killing them or making them sick. Seems to work best if you can stop the flow of water in a stream or partially drain the pond and apply it direcly to wet algae. However, I dump it in the water and it sticks to the submerged algae and does its damage. It contains sodium percarbonate and sodium carbonate. When mixed with water it turns into hydrogen peroxide then degrades fairly quickly into oxygen and water.In addition to this treatment I have a pond filter that filters and flows 24/7 as well as a copper electrolysis system that releases copper into the water. The combination of these treatments help to keep my shallow fish pond fairly controlled algae-wise.

what I was looking for

I normally use a liquid LG I tried this it works great I love it the only problem I had what's the measuring cup was buried halfway down to the bottom and I didn't know it was in there until I was half empty but I'm definitely buying it again

My pond is the cleanest it has been in a long time, without having to drain it, clean and start over. Great product...

My fish died. 4 tilapias, 2 mudfish, 1 sucking fish. Don't get this poison.

Works great, fantastic price!

perfect just what we needed.
