HELP , my husband and I are ready to close our pool for the season, but after reading some of the post here, we're confused. We understand raising the chlorine level and draining the water justy below the skimmer. We keep seeing that some hoses are supposed to be disconnected. The problem with that is all of our connections are PVC pipes. Can someone please give us step by step instructions on how to close an above ground pool. Thanks in advance for any replies.
