How to get rid of string algae in our ornamental pond.?
We've tried 4 or 5 different chemicals including clarifier and algaecide. We have a barley pad floating in it, we have a fountain running and a creek running into it, we also have about 30-40 comet goldfish and koi, and about 6 plants growing in it as well (water lily, cattails, irises) although they are not fully grown yet. The algae lines the entire bottom and sides and is about 3 inches thick. Would a pond vaccum help? We don't know what else to do :(
I have found that Microbe LIft PL works very well to eliminate this stuff. Get as much as you can out and then put the Microbe LIft in according to directions. It's an enzyme and won't harm your fish or plants.
You don't need a pond vac at all.
