I notice that no one puts rock in there qt. When I got my live rock I had a lot of little rocks that came with it. nothing I would use in my tank. there more like pebble size. I never planned on using them in the DT since they were way to small. I had so many that I felt a few would benefit the QT and help cycle it. I never took them out. I'm I hurting anything by keeping them in there?
