I've been fighting BBA on the Anubias for a while now and it seems to be getting worse. I dipped it in some PP (Potasium Permanganate) a while ago, but it had zero effect. So I put the plant in a bucket and squirted it with about 60 ml of Excel and then filled the bucket with water and let it sit for about an hour. Some of the BBA seems to be turning red, but the impact wasn't miraculous. Maybe I have to wait longer? Also will the leaves with the red BBA become algae free or should I just clip them?
