Hold on here now...I'm getting confused...Reefman says, "depends, mostly on the size, but usually they consist of Diffrent varietys of Macro Algeas, LS and LR. Lights usually are on 24/7 (mine are) but some people like to play it a diffrent way."
But @Knight says, "a refugium usually consists of diffrent varietys of macro algeas, LS and LR. Lights usually are on 24/7 (TheReefman52's
are) but some people like to play it a diffrent way"
who's do I believe?!?
