How big of a sump? Personally, I think the return pump is to large. Will be having really high sump flow and if sump isn't big enough, can get microbubbles.

I have a closed loop for tank flow, on my 150g, and a my sump return pump is about 600GPH to tank. was 1300GPH sump return and found a bit of bubbles(70g sump). But what I really found, was the pump would drain sump before the tank drain would catch up upon restart. I have 5g of 'play' in my sump for starting etc, and it usually pumps all of that into the tank, then sucks air, untill the tank drain catches up and everything equals out. Slower return pump, the faster it equals out and the less it pumps out of sump untill it catches up
