I'm not an expert on this but I just got rid of those algae in my tank. It was brown black brush algae. It didn't look as bad as the picture but it's like brushy and hard to remove by hand algae. I think it was bba. I had this covering my crypts. I had those when my nitrate was at 3ppm and PO4 at 0.25, pH 6.9. I just started dosing npk 3 weeks ago in that tank and those algae's were gone in a week (nitrate 10ppm, PO4 0.75ppm, pH 6.9). I have no idea why they're gone nor why I had them in the first place :roll: . But I think getting the right level of npk must have something to do with the dissapearance.
