One more question, while I'm thinking about it: All of my plumbing terminates right below the water line in the sump. You guys had mentioned an exhaust hole on the full siphon drain. Is that above the water line in the sump? How big should I drill it to not impair the siphon?
Bob, I really don't mean to hijack your thread. With it being so slow around here, and since you just did this to your tank, I figured it wouldn't be too off topic. Thanks again!
