HummingBird Posted July 21, 2006 Report Share Posted July 21, 2006 Sounds like the dreaded blue beard algae. Although it's called an algae, it's actually a type of cyanobacteria. The ways I know to get rid of it are: -Double dosing with Flourish Excel -Antibiotics (this is a pretty extreme method, I'd try everything else first) -Siamese Algae eaters (they'll eat it, apparently) And of course to discourage it's growth and keep it gone the simplest things to do are keep your nitrate levels down (by doing regular water changes) and have a ton of plants (which will use phosphates before algae gets a chance, and help keep the nitrates down as a bonus.)
