Live rock in cannister filter
I have an eheim 2217 cannister filter in my FOWLR setup. It's currently holding some mechanical filter pads but I'm concerned about nitrate buildup (as I don't see myself being able to clean it often).
Would live rock be a good addition to the cannister? I have zero light in the cabinet where the cannister sits. Will the live rock be OK in a high flow zero light spot like a cannister filter? (or will it mostly die and cause more harm than good)
