I am not the equipment guru around here by any means. But just wanted to share what I have on my pool since the pump size for this pool is being debated. I have a 27ft AG pool (approx. 19,300 gallons) and I have a 1/2 hp full-rated inground pump and it works just fine. I'm inclined to think that a 3/4hp on your pool should be plenty. Just my $0.02.
