Bubble magus just got serious!

Honestly, I don't see the point of a controllable pump on a skimmer. The pump's output should be matched to the skimmer. Making it adjustable just gives the end user one more setting to get wrong and have to balance with other settings. I prefer just an adjustable output (wedge pipe/gate valve etc) to get your water level in the skimmer right and maybe an adjustable volute/venturi to adjust the air draw. That's all you need. Why add another complication?
