I was just thinking I need an update on this tonight, well after so many skimmers I took what I have liked from them all. I like the bk mini collection cup. just grab and go. Very easy to clean. I like the water coming out the bottom of the wedgepipe. So yes it has that too. THe Tunze pump is really quiet. If I had it to do over I would of gotten the 9420 over the 9410. the pump I have was pulling about 28 scfh. Not bad at all but i realized I needed closer to 1000 lph after I built the skimmer. So I had to mod the pump slightly. put a little mojo on it :) and brought it up to exactly 1000lph of air. I ll go take some pics. Working well I just cleaned it yesterday.
Here is a little scfh to lph conversion for your FYI
