Frustrations with Vertex Omega 150 Skimmer

[kamloops_reefer]

anyone else running this skimmer at 9-3/4" water depth is close with problems? I have the riser tube open 100% I also have the adjustable nozzle (where the water comes in) turned out almost all the way

this thing is skimming wet, not very dark. When I pulled my filter socks and put new ones in, this went crazy and just overflowed the collection cup like no tomorrow.

one other concern I always had... the skimmer doesn't' really seem to sit level - the pump weight tilts it a tad bit, and the weight of the cup usually brings it to plumb. I could be paranoid, and granted with all the problems I've had with this thing I should be - but shouldn't it be plumb?
