What do you think is more energy efficient.......running the pump on low 24/7 or high speed for 10 or so hrs./day?
2 speed pump?

I’m going to guess low 24/7, but I don’t know for sure.
But skimming and filtering 24/7 makes my heart go pitter patter.

It looks like your pump runs 1750 rpm at low speed and 3450 rpm at high speed. Doubling pump speed requires roughly 7 times more energy. 24/7 would be far more efficient. Here is an efficiency chart created by @PoolGate. Look at RPMs and Watts...

My 2 speed pump moves 1/2 as much water for 10% the power on low speed as opposed to high.
Using the actual power consumption of my Hayward Powerflo Matrix 1.5HP 2 speed and 250lb sand filter :
at 14 cents per kwh (not sure if this is the actual cost at this time or not but close enough)
24/7 on low speed (171 watts) which is what I do : $17.50 per month
10 hours per day on high speed (890 watts) : $38 per month.
I don't know how much water it moves vs high speed but it's more than enough and I'd even say it skims better in low because the water slows down so the skimmer pulls in more off of the surface.
From what I can tell, this system uses 19% on low speed.
