Micro-Bubbles

Hi All, I am having troubles with tiny bubbles getting back into the tank. I have shut of the skimmer so it's not that. I am guessing it's from the return into my sump. Any suggestions would be great.
Currently my plumbing is as follows overflow->sump->return pump(rio 3100)-> main tank
I also have a maxi-jet 1200 feeding my refuge and overflows back to sump
Thanks
Martin

First you must find out where the bubbles are originating. This will help us solve your problem.

Pump might also be cavitating and creating the bubbles.
Just my 2 cents.

Thanks Guys, I believe the problem is coming from the overflow to the sump, then the bubbles get sucked by my return pump. Can i minimize the turbulence from the downward flow into my sump? My connection from the overflow is flex tubling with a slight angle, so it does not come straight down HTH
Thanks
Martin
