Maybe I'll wait on this and consider a refugium retro-fit kit for a spare 10gal tank that is lying around. Not sure if it will fit near the display tank yet. I could put it on a shelf but the weight is a real concern.
Any opinions on mud bottom verse deep live sand? Macroalgea sounds easy but pods
are another question. Don't the little buggers just get pumped/drained out of the refugium and into the display tank? Are bristle worms advantageous to the refuge and display tank health?
