I've got a 180G - dual built-in overflows, to a 30G sump (small, I know). The overflows drain into 2 sock filters, into a section where an Aqua EV-180 feeds from and returns to (it's outside of the sump).
I have standard bubble trap baffles - 1" apart, and I've added foam screens to the bulkhead strainers that go to 2 pcx-40 return pumps, but I'm getting a good deal of micro-bubbles from the return. Not a huge amount, but just enough to cloud the water a bit.
I have enough water flow from the returns and two 650GPH Koralia pumps that the tiny bubbles can't just float to the surface and pop.
Any suggests for dealing with microbubbles returning from a sump? Do I need a finer foam mesh over my bulkhead strainers? I don't want to restrict the flow to the pumps in any way.
Maybe two more bubble trap bulkheads? A bigger sump might be the answer, since I'm pushing around 1200GPH flow through it, but I'd like to find a solution without going that route.
