So I've put up an Intex rectangular pool that's 16x32 52" deep. I've had several intex pools in the past including the larger 3000gph sand filter they make which was a great filter . This pool came with a 2100gph or so filter that holds 75lbs of sand. It's not really good at all at moving the water... it really kinda sucks. The water also doesn't spin in this pool like a round one. So I've bought a 4500 gph 175lb sand filter, a real skimmer and two inlets.
Intex has really poor placement but I understand they have to stay within the reach of their hoses. I'll be hard piping all of this. I have two designs worked up but I can't decide as I don't know which will move the most water. With the sand clean I should be getting at least 2000 gph out of each inlet. Can any of the pros look at my pic here and see which will move the most water.
