Recently have been having a minor outbreak of BBA ( Blackbeard Algae ) in my 20 long that currently has a Fluval 206 and an Aquaclear 40 and an air pump powered dual sponge filter running on it. My light is a Beamswork that is on 8 hours a day religiously. My inhabitants are 6-8 young guppies 4 Emerald cory cats 2 oto cats and 1 clown pleco. I've manually removed a good amount of it. I have a pretty heavy plant load IMO. and do regular weekly 20-25% water changes and on occasion a filter cleaning without killing any beneficial bacteria. ( Very familiar with the importance of the Nitrogen cycle ) My tanks are always crystal clear but this one has been a bugger to fight the BBA...any advise would be grateful
