Hydrogen peroxide (H2O2) hyper oxygenates the water. This sudden increase in oxygen destroys the string algae. Using 3% Hydrogen peroxide (the kind found at your local drug store) is safe for fish when used in the correct dose. Using 16oz hydrogen peroxide per 1,000 gallons of pond water will eliminate string algae in a matter of days.

Do not add peroxide directly where fish are located. Direct contact with hydrogen peroxide could burn your fishes' gills. If you add it to your skimmer box, by the time it goes through your pump and waterfall, it is diluted enough and safe for your fish.
