Man, this thread's got me paranoid. Gonna check my Acans tonight. Dynamox, keep us posted if the peroxide works, yeah?

Not worth the risk. Erythromycin nukes your biofilter, and black band's often a combo of bacteria and cyanobacteria. Stick to mechanical removal and dips.

Update: Did the peroxide dip and fragged the healthy parts. Lost about 20% of the colony but the rest looks stable. Thanks for all the advice, everyone.
