It’s a newish tank and I have algae mostly just growing on the top of the aquascape. Should I be brushing the rocks or increase the CUC? I only have 3 trochas that even go on to the aquascape. The other snails mainly stick to the substrate. I’m running the lights only 12 hrs and 4 at peak.
side ?, is the red/brown stuff in a few spots algae too?
