Black beard algea

[DGC]

well could not find any glut but flourish excel i found in the most unlikely place has worked like a bomb, 2 days and the algae went red, 4 days and it started falling back, 6 days its gone,

Only 2 types of algae to go and i have been through the big 5 LOL

the bba will come back unless you dose with excel forever. I suggest you find the cause of your bba (it is co2) and solve it (more consistant co2 with a proper balance of light, co2 and ferts)
