I think the mag 24 may be a bit much for a 40 breeder sump.
So I'll drop it to the Mag12. and run PVC
to increase my water flow. These barbed fittings dropped my GPH
pretty bad when i went to flexible tubing. Plus the reason i jumped to the 24 was I have two Overflows rated at 1800 GPH
each and with the 12 it was gurggling no matter what i did with my standpipes. I'll just keep fiddling with them or modify my drains to a 1" drain instead of 1.5" and that may slow the drain down enough.

crp 90 overflow from everything I read I figured I needed about a mag 24 turned out it was way to big I even had a valve that was more than half shut and there was still to much water someone on here suggested a mag 9.5 so I found one on Craigslist for 20 bucks and it is now a perfect match for my overflow
My 24 pushes a lot of water for sure and i really would rather drop back to the mag 12 anyway since i liked it better. My overflows will just have to be tweaked a little i guess.
