I am new to owning a pool. I am having issues with getting the pool to circulate the water to move floating debris to the skimmer. My pool is older and only has two return jets marked by arrows in the picture. Because of the shape of my pool the debris either collects in the cove to the left of the picture or my the steps. I can not seem to get the right jets or adjust them to circulate the debris to get it to the skimmer. Any help is appreciated.
