The algae in thicker patches tears off the rock pretty easily, but it is near impossible to scrub off a powerhead. Perhaps a hydrogen peroxide scrub on the powerheads is in order? Is this turf algae? I currently have 2 clownfish, a tomini tang, a lawnmower blenny.
Temp - 79degF
Nitrate - 0-2 ppm
Ph - 8.0

I have hanna phosphate reagent on the way.
