Hi Folks. Did a quick search on previous posts and was unable to find an answer to my question, which is this: what is a good size for a refugium (percent of display tank size)? As large as feasible, or is there a point of diminishing returns. Also, are pods likely to get too mangled by pumps? Gravity feeding it into the tank is not feasible for me. I might just be using it as a macroalgae production facility, as well as a maximum security detention facility for some bad guys I've got, but don't want to kill (mantis, reef lobster, serpent star). Thanks!
