I have a 10 gal s wtr tank wth 5 gaL sump how do i eliminate micro bubbles coming from the sump?

Question

1 p skimmer 1 1200 maxi jet thats in sump hooked to 1\4 in hose in main tank i have 1 maxie 400 for current and a catilina 900 for the return back to sump via 3\4in pvc and 3\4in hose +2 waliworld pumps in sump for filtration

Answer 1

put a divider in the sump that separates the sump into sections that the water will just over flow.  have one side that water flows into (keep the skimmer on this side) and pump out of the other side. Keep the return pumps intake as close to the bottom as possible  

The over flow will only allow bubbles at the surface to pass and your return won't get  those
