I have a 15k gallon fiberglass pool with two skimmers and two returns. How should I optimize the water flow? The returns are directly under the skimmers. I currently have then pointed downward. I also have two drains in the side wall below the skimmers (wasn’t my idea) that are in between the skimmers to draw from as well. Pool looks the best when returns are pointed up because of the water ripple, but i think I get better mix when pointed down and away from skimmers. Anybody have any thoughts on this?
