I'm looking for a larger overflow box - I've got two j-tubes in the one I have now, but the 1" drain pipe isn't enough to handle much over 300gph. I've thought about taking it apart and building one with two drains, but I don't think I can fit two in there with 2 overflow tubes.
Any suggestions for decent (quite) overflows that will hold a siphon, and handle say up to 600gph? Are the CPR's any better than j-tubes?
