Wondering if anyone here keeps freshwater aquarium and battled black beard algae? (the fuzzy black variety)...Aside from rehoming the fish and nuking the tank with bleach (which I'm reluctant to do), are there any OTC/DIY remedies? I have it and it keeps coming back...it's a pretty darn hardy variety. I've tried Tetra and Top Fin algae treatment but neither seems to work. I picked up a couple black Molly's because they supposedly eat algae and they do pick at it but it's hardly getting rid of the algae. Any ideas?
