Re: Black Spot Algae? Anyone figure out a way to get rid of this?
I have a lot of it on the older leaves of my Anubias barteri var. 'Petite'. It isn't a spot algae, really, as it eventually turns into a larger mass. It's more like the diatom algae, but a much darker color, and this is in an established tank.
Also, unlike GSA, this algae appears to survive Excel dips. |
