Refugiums: Yay or Nay?

[Animal-Chin]

I'm not expert but I think mine helps keep the water clean. I have a pretty big one, I'd say 12x10x10 packed with cheato. I trim half of it out every month or so and it grows back quick. Its teaming with life from pods to little star fish. So I keep the thing going...

Yay. I always have part of my sump converted to being a refugium with some chaeto, other macro & live rock (rubble) for extra biofiltration/nutrient export & pod production to add live food into my display.
