Hi! I'm opening the pool during this quarantine and have hit a snag. I've noticed the debris floating on top of the pool is not being sucked into the skimmers? Water is flowing; pump is primed; slide is running; jets are pushing; but when I look into the skimmer, the water appears to be standing still and nothing is being sucked in. I know water is flowing through there because the pump is staying primed. Pressure looks good and the slide is running strong which usually means all my flows are fine. Any ideas? I'm tired of skimming by hand! My pool has no main drain, by the way. The water to the pump only comes through those two skimmers.
