For the first time in 15 years the Pool guy put in these directional return line fixtures at $5.00 each. He said it will increase circulation. But they are not movable for some reason and dont come off. Do you know if they are possibly the wrong side, or way over tightened???
Also they increase the flow alot so its almost a spa effect and some of the water on each of the 2 lines goes along the walls quickly and a touch of rippling above water. Won't this cause more evaporation. He has the shallow end ponted at a left right angle to the end wall and the deep end toward the shallow end.
