I use a small river rock to weigh down the hairnet in my skimmer. Maybe 2 x 3 x .5 inches. When I was changing the hair net in the skimmer yesterday I dropped it in. I immediately went to turn off the pump. We tried using our wet vac to suck it out to no avail. I've called the PB for recommendations. Until I hear back, can/should I run the filter with the skimmer off, just using the main drain?
