  • Buy this if you want clear water when you open your pool next season!
Style: Kit Only Size: Deluxe
We used this last year and this year to close our family pool. It really simplifies the process and does the job great! One stop shop to get everything in one shot! Keeps the water quality good throughout the off season, algae growth down, and chlorine levels in check so you have a clear pool when you open the following season! No swamp water with this kit! ... show more

  • Save time and money with this hassle-free pool closing kit!
Style: Kit Only Size: Deluxe
This pool closing kit exceeded my expectations. Everything arrived together in one box, even though the listing mentioned items might ship separately. The instructions were clear, easy to follow, and made the process simple. What I thought would be an all-day project ended up taking only a few hours, with just a few bottles to pour in at timed intervals. As a first-time pool owner closing for the winter, this kit gave me confidence, saved me a significant amount of money compared to hiring a service, and made the process feel effortless. Looking forward to opening in the spring, but I’m very pleased with how easy and effective this kit made the closing process. ... show more
