I have a 24' round agp with 1hp hayward pump and a Hayward sand filter. I cannot get sufficient circulation throughout the whole pool. The side opposite the direction the eyeball points always ends up with standing dirt on the floor and filthy walls. The side the eye points stays clean. I've tried down and left, down and right, and down with straight across. I've tried varying degrees of down as well and always seem to have dead spots. Amy thoughts on how to resolve this? Should I look and a specialty eye such as "the circulator" or is there a magic direction for my eye I can't find?
