ok then i have another question. if i put the skimmer at the surface (mine has screws to adjsut its height), then the flow slows to a trickle. if i put it further down, i get a better flow, but the surface gets icky protein film on it. the box is supposed to be a 600gph flow, but it doesnt even seem close to that. it has a 1inch bulhead that it barely utilizes, and the box it self has about a half in of water in it at all times (working on a durso standpipe to do something about that, but i want to fix this flow issue first.)

actually ive just turned off the sump and overflow. im having trouble getting everything "balanced". is it supposed to be a delicate balance of overflow vs return pumping or am i just doing something wrong?
