If it works for you than great, have you tried blocking off the siphon to see what happens? 10X turnover in a sump is on the high side, especially with the new DC powerheads.
Sorry to say you'd lose that bet . Water level in the Durso side IS higher than in in the siphon side, but not by much. I'm running a PanWorld 150PS from my basement sump, so probably only in the range of 800 or so gph when accounting for head and friction loss. If you figure both overflows are handling half, then 400 gph down the durso, less if you figure they're not equal. Either way durso is not noisy at all (no fluctuating levels) and the flow through that overflow is sufficient to keep the water moving behind the weir. Siphon, of course, is completely silent.
