I have a FOWLR tank. I had about 50lbs of live rock in there about three weeks ago. I had about 20 lbs of dead live rock in my closet and about 10lbs of base rock in there with it. I put all 30 in the tank so I could have enough where I could get rid of my HOB filter. When will this non live rock become a filter?
