I turned on my pump this morning to add some stabalizer. I added it to the skimmer basket and checked the pressure guage. It was at 20 PSI, the normal pressure for the filter.
I heard some bubbling sounds coming from the pool, and I went out to check. There was little or no pressure coming from the returns, and the pressure guage dropped to 0. The pump is still running however.
Did I do something wrong? did I really mess things up?
