I have used it in several ways against different types of algae.
Remove driftwood or rock from tank and pour on the H2O2 straight (3%). Let it sit until I am ready to put it back, then a quick rinse in a bucket of water. The remnants on the branch are no big deal. Very good results on BBA.
Drain the tank for a water change, whatever will expose the algae and squirt some H2O2 into the densest mass of the algae. Dose 1ml/gal. Reasonable results on BBA, though a second treatment sometimes helps.
One-Two punch @ 4ml/gal with NO LIVESTOCK. Spotty results. I think the water circulation portion of the instructions is very important. Best results in tanks with best water movement.
Add H2O2 to an aquarium where the fish are gasping for air, helps. Obviously I followed it up with a big water change to remove whatever conditions were causing the low oxygen in the tank, so the H2O2 is only the first step in the treatment. But it gave me long enough to get the new water prepared.
