I took a friend out Saturday and we picked up 30lb.'s of LR from a member. I just raed that people who got coral from the same set up noticed red bugs. ::The rock is in a brand new tank and except for what ever life was on the LR that is all that is in the tank. Do we need to treat it for red bugs? If we do how do you treat it. Do we treat the whole tank or remove the rock? What about the sand?
