What Mark said. You need to keep that pump on the skimmer. For future reference, pumps should never have any elbows on the intake line and the intake line should be as short as possible to reduce any flow restriction. I see the water is going into the skimmer from the furthest left compartment in the sump, where is the water going back to? Returning it to the second chamber (as far to the left in the chamber as you can) would be ideal in your particular sump. You should then add at least two more baffles between the second sump and the return pump. With that amount of flow in the sump you will need multiple baffles to filter out the microbubbles from the skimmer. The last baffle before the return pump should be off the bottom, not touching the bottom. So if you use 3 baffles your baffles would be off the bottom, on the bottom, off the bottom. I would suggest 1.5" between baffles and 1.5" off the bottom....I think, what's the width of your sump?
