Substrate Free Tank Husbandry (Bare bottomed)
My issue is as follows:
Most of my SPSs are very lightly colored (popular!), BUT, I have to clean my glass from diatoms every couple/few days, and recently, it has gotten so bad that diatoms are now growing on my very faded monti. caps.
So: what is wrong? If I had dark corals, I'd know too...
