Substrate on top of BGA?
I have a 5.5 gallon betta tank. I have FLUVAL STRATUM as the substrate. I need some more. There is some BGA on the substrate. Would it be OK if i put substrate (FLUVAL STRATUM) on tp of the Blue Green Algae? Would something bad happen underneath the ne substrate? I sprayed some Hydrogen Peroxide on the patches of BGA, but still..
