I would redesign the sump a little bit. To help you follow lets call the current fuge chamber 1, the current pump section chamber 2 and the intake chamber 3.
I would plumb the system to have your intake lead into chamber 1 then it will flow into the second chamber. I would house the fuge here in the second chamber. This will make the baffles separate the previous two chambers from 1 and 2. Baffles should always be at the end of the sump as they are designed to remove micro bubbles. With your current configuration the fuge will be dumping tons of these bubbles in the system. Lastly I would use chamber 3 for the return pump.
To accomplish this you might have to raise or lower the baffles between chambers 2 and 3 but probably not. It should be as simple as just reversing the flow of water. Also it would be nice to add a filter sock into chamber one where the intake water comes into
