I need an id and cure for the pictured algea. Bushynosed plecos browse it, but don't remove. It is very attached to leaves of sags and vals also. Showed up when added some plants and is only in this tank. Extra dosed excel this morning so might help. Going to get some ottos or sae's this week and need to know if they will touch it either. Took out a couple of the anubias that were just getting it and put in a pail with algeafix and extra excel also this morning. Any more ideas?
