Can anyone suggest an in sump skimmer for me?

I would normally recommend the BM or the SWC normally, I just bought a SWC 180 and I am wishing I had got the BM now I think. Still having a hell of a time dialing this skimmer in. Sometimes it works great and other times it doesnt, overflows sometimes and other times it puts way too many microbubbles in system. Water levels are controlled by ato and not an issue imo. If I can't lock this down soon I am going to put the old skimmer back in sump.
