Hello everyone, I think my mag 12 return might be cavitating. I have lots of micro bubbles in the display. When I hold my ear to the sump where the 12 is located I can hear it cavitating I think. Sounds like a burst of bubbles every few seconds. Sump is located approximately 7 feet below...

I'm looking to swap a mag 12 for a mag 18, I would toss in some cash to offset the trade. PM me if you are interested.
