15ft Round pool with 1.5hp pump

I think a 1/2hp pump would be plenty.

We have a 3/4 horse pump/filter "Package" by Intex that takes 75 lbs silica sand. Our pool is 15' X 48" and I'm going to have to restrict the flow going into pump, It pushes water out of the pool inlet too hard and fast. If I had it to do again, I'd go with a half horse pump.
