Hi ccLansman,
I'm new to planted tanks and I've also had issues with BBA and BGA previously.
Thanks to the advice given here, I managed to win the battle.
Hope my experience in the recent battle can help you.
1. This can't be said enough. Your lighting is too much. Even if there's no BBA, some other algae issues will arise with that much light. I've tried 5wpg and it was disastrous. It's like driving an F1 vehicle full speed and into an algae wall.
Patches of algae can appear within 1 day.
Reduce the lighting. I know using wpg is not a good guide, but 2wpg is a good start for us beginners.
2. Circulation. Chris and Hoppy reminded me many times that circulation is very important. Good circulation will distribute nutrients well around the tank.
I've had areas in my tank that had lousy circulation. Guess where the BGA appeared. (no prizes for correct answer
).
Noticed in your earlier post that your powerhead is blowing back at the rainbar.
I.e "RAIN BAR" ---->
