Here is with lights on. Weird, but absolutely not s strand of algae. I went through 2 bouts of gha, at about the 1.5 month mark and 3 month mark. I ran gfo after the cycle and got all the gha out plus the idol loves eating the stuff!
Today light feeding of frozen for the smaller fish and s little piece of nori for the tang and idol. I have to keep nori in the tank as the pbt is not eating frozen or pelleted yet, and there isn’t enough gha in my rock to sustain it either.
