This has been irking me for some time. A refugium should be a refuge for anything that lives in that environment, not so much so if I'm tossing half of it in the trash every couple of weeks. I've found baby cardinals and mollies living in that small section of sumps and will catch them before I grab a handful of chaeto and toss it out. FWIW, I run one before my skimmer and after my returns.
I understand it's part of my filtration system and would probably not utilize a reef system without one, but to call it a refugium when I am literally throwing away 50% everytime just doesn't seem right.
