UPDATE...........I ended up ordering the 1HP 2 speed Hayward pump and the 300lb sand filter. The pump is strong enough on low to even vacuum with but drastically less pull than my old pump. I was so relieved, some had said low was too low to even use which would've defeated my whole purpose for buying a 2 speed. Not sure what their set up was but I have a 24 AG pool and the pump and filter are within 2 ft of the pool so I have only short runs of pipe. Not sure if that has anything to do with using low but anyways it seem plenty strong so far. True the water is gently swirling so not sure if that will leave "dead spots" in my pool, whereas the other pump was so strong the entire pool was "whirl pooling" so def no dead spots, but was too strong for sand filter, water was just blowing thru it. Will post here a final result of whether or not this new smaller pump and bigger filter solved my filtering problem.
