I have my overflow near the intake of my protein skimmer. I also put a powerhead in the sump.
I did the exact same thing for about a year when I wasnt running a sock. Found that the maxi-jet 900's I had for my GFO and AC reactors were constantly clogging, and the reactors themselves were getting significant gunked up.
How did you address the issue? or was it just taken for granted that this would happen.
