I have a 250g tank and ran 1" for my siphon, durso, and return. I upsized my non-durso emergency drain to 1.5 inches just because I could. I figure it will give me a little extra margin in gph in draining if I ever need it.
My return pump will put about 1800 gph back into my tank and a 1" siphon at 11 feet of drop (into my basement) gives me something like 2200 gph. I'll adjust the siphon with a gate valve in the basement to get it to match the return rate from my pump.
