I started reefing back in September with a 20 gallon tank, I just upgraded to a 40 gallon. I have 60+ pounds of live rock and around 50 shells lining the back of my tank. I have an AC70 HOB filter that I modded into a fuge with Chaeto in it. My question is: Would it be safe to get a Mandarin sometime in the future with that set up? I was thinking June or July-ish? Longer? Even at all? Would I be able to tell that I have a plethora of pods that would suffice?
