Fiberglass Pools – Kingston Pools and Hot Tubs – Knapp’s Pools and Hot Tubs by kingpools_admin | May 13, 2016 | Uncategorized | 0 comments What a beautiful calm morning yesterday. Took these pictures of the pool. The water looks incredible using Pristiva Salt System for Salt Water Pools. Opened the pool a week ago. Haven’t turned the heater on yet but will be doing that this week. Submit a Comment Cancel replyYou must be logged in to post a comment.
