I think it's a mistake. It's not that big a pool. I have a 16x40 rectangular with a 5 1/2' deep end and only one return and that's all I need.

If your circulation is poor, you have other problems you need to diagnose and address first.

Most AG pools (like ovals) are built with pre-cut points in the walls for fittings. Cutting your own can open them up to corrosion since the cut isn't finished.

The ONLY think I would consider if I were you, is adding solar panels as the "excuse" for a better-located return.

In general, returns should not be low. If you want them to move lower water, you put in a movable eyeball and point it down.
