Here’s a typical open loop system.

Note collector area should be 50% pool area.

Now you can go low tech, if you have room, just get corrugated iron sheet, paint it black and pump pool water into a distribution line over the top collect into a gutter at the bottom and some pumps and bang… I’d be surprised if it were more then a grand.

If you want to go cheap, paint a roof section black, mount pipe up there, and distribute via gutters. Collect return flow and filter before dumping into the pool

Three hundred bucks…
