I have a new pool and am curious if my pump is set up for optimal operation, in terms of energy efficiency. I have a 17k gallon pool / spa combo, with the spa raised up 2 feet and spilling into the pool. My equipment is in my signature. My pump is currently set at 2465 rpm and runs at the same speed for 9 hours. The tech who set up the equipment said it is set up correctly, however, I have been reading a lot of information saying I should run it lower for a longer period. Any help is appreciated. Thanks!
