I finally added a Aqueon Proflex Sump and an Lifereef overflow to my RSM 130. I have the overflow in the back chamber and the return goes into the main tank. The question is have is.....If the grate going to the back chamber gets clogged I could overflow my tank. I was thinking of drilling some additional holes in the wall between the tank and back chamber. Any ideas if this is a good or bad idea, Thanks Don
