![]() your right, it doesnt matter if the rock is in the sump or display, it filters just the same......anytime live rock is exposed to the air, it will cause die-off of the bacteria....its the main reason a tank cycles when you bring your rock home....you can minimize this by keeping the rock in saltwater while you are working on the tank, but there will be a cycle of some sort....might be small and barely noticeable, might be larger and troublesome......kinda the risk you take when you mess with the tank
