I had a small problem with bba it really only grew on the anubias.ive been addressing this by increasing circulation and upping the c02 and by moving the diffuser into different locations within the tank to find the ideal spot for co2 distribution.Last week i also purchased 3 sae (already have 3 ottos).But these sae's are superb they are going through my tank like a dose of salts. The bba is disappearing off the anubias you can actually see where they've been. 3 great additions to the tank.
