Built a DIY
skimmer and it was working great. It is in my sump, you can view in my post in DIY
awhile back. Suddenly this thing is skimming so hard and fast that it's pretty much just taking water straight out. I can't see how it's pushing straight water up and out over two inches. Any suggestions? I haven't made any real changes to this thing and I just can't figure it out. Should I just raise the height at which it "foams over" to the collection cup?
