minimize micro bubble from sump

[tranvictor]

You can seperate your skimmer from your return pump using two more baffles. The baffle nearest your skimmer will be attached from the sump bottom. The second baffle (closer to the retrun) should be attached from the top of the sump. That way the bubbly water will have to go over the first baffle and since air is lighter than water the second baffle should catch the bubbles with only water going to the return pump.
