I'm so frustrated, then.... I've had bba for a few months in one tank (I thought it was gone, but spouse has helpfully pointed it out) and it's a CO2 tank with 3 bps. Low CO2, how can that be. I hate algae!!!!
Just curious to what size tank you have?? How have the fish been responding to that level? I have read multiple posts on here that guys even have more 3BPS to the point where they could not even count them. Im guessing the more plants in your tank the higher level of CO2 needed based on the bio load of plants you have.
I just got my CO2 going in my tank at only 1BPS and I now have more BBA then I did before. I will def be increasing my CO2 levels tonight and hopefully that will help. I do have ALOT of plants in my tank as well.
