Change of plans for the pumps. I will be selling my 1/15hp pond pumps in favor of some high end pool pumps.

Was out messing around with my pool pumps today. They are high efficiency Pentair variable speed pumps. You can set them anywhere from 400rpm to 3,400rpm and they display exactly how much power in watts they are using on their lcd display.

At 3,000 rpm they are loud pool pumps blasting away and sucking 2,000 watts.

but when I dialed it down to 750rpms where I would run it on the aquarium pumping 1,200 gph it was whisper quiet and pulling less than 120watts !!!!

This will also allow me to exactly fine tune how much water the pump is putting out. just simply push a button on the pump and speed it up or slow it down.

Insanely expensive at $900 a pop, and I'll need two, but the savings in electrical cost should offset it in a year or two.
