Kit Had What I Needed

I received what was listed in the description of the closing kit. The pH and Chlorine level for my pool were right before I started, so after brushing and vacuuming the pool I was ready to start closing the pool. The instructions were very clear and easy to follow. Now we just have to wait and see how things look next spring when I open my pool.

One-Stop-Shop Closing Kit

We have used the Super Pool Closing Kit Up to 35 multiple times and subsequently opened our pool to see 30,000 gallons of clear swimmable water. The chemical distribution process does not take long. Just follow the instructions, cover the pool, and enjoy your winter with confidence that you will see beautiful water in the spring.

Best products

I love this Deluxe pool closing kit. I've used it every year since 2006. And I will continue to use it. The instructions are very easy to follow super simple to do and I open my pool Every Spring to Crystal Clear Water. I get all my products from In The Swim and my pool has looked perfect from the day I put it up.
