Just set up this skimmer today. Where do I want my collection cup in relation to how it is now ( please see pic ) ? Do I want it lower so more of the white bubbly foam essentially pours over the top of the tube and into the cup... Or higher so the stuff doesn't even reach the top at all... Or basically right where it is so the stuff reaches the top but doesn't overflow? I realize this isn't actually "skimming" yet due to break in period, but I need to know how to let it run. Thanks!
