i am having a repeating battle with some BBA and staghorn algae good thing its still limited to a certain portion of my tank and havent spread out. the last time i wiped them out completely was by heavy excel dosing in my tank... 3x the dose for 4 days. it cleared it out, but at the expense of my amanos. apparently my amanos dont seem to like eating the stringy staghorn algae would otocinclus catfishes eat them?
