Yeah, I switch from 3/4 inch tube with 1/2 exit port that was with the original set up.
to a 1 inch from start to finish, and my tank can hardly keep up with the amount of flow.
Had to back down from the mag12 back to the mag9.5 just to keep the water in the tank/sump.
CRAZY!!
Redid my sump to handle the volume..... we'll see!!
