The highest efficiency occurs when the power curve intersects with the pressure curve. So you'll notice I used the word "likely" as it may or may not use more power, you would have to hook up a power meter to figure that one out for sure.
But thanks for clearing that up  |
Ya, that is true. But, need a flow meter and a ammeter to truly find the curve. Ammeters I have lots of, but lacking on Flow meters.
BTW Phanman, the Mag 18 is gona have a TON of flow. I tried one on my 45g. had it submersed in the sump. It heated the tank up to 85* just running it alone. Granted, if you run it external, it wont put as much heat into the water, but its still going to. Presently I have a Mag 3.5(50% restricted) and a Quiet one 3000 in my tank and thats putting to much heat into it.
