What is the brown growth on this driftwood?
I think this has been answered before but I couldn't seem to find it anywhere.
I put in a new piece of driftwood and around the same time that I had some low CO2 problems.
On the driftwood and moving to the substrate and plants is this brown fuzz growth. Is this algae or is it some other type of growth coming from the driftwood?
