  • Great kit for a fair price !
    We have been using this pool closing kit for years ( This being the 4th ) It's simple to use ( directions included ) reasonably priced and our pool is crystal clear each summer when we open it ! You will not be disappointed!!! It's not the cheapest kit out there BUT it's certainly the best quality ( we've tried 3 or 4 other brands) You get what you pay for and this is both amazing and fairly priced ! Win win !
  • Great value
    It is easy to use and seems to help, but I certainly don't open to a crystal clear pool. However, it does seem to help, is easy to use, and a great price.
  • Reliable Product
    I have used this product over the years. Very straight forward and easy to use. Keeps pool water clean over the winter for easy start up in the spring. Reasonably priced.
  • Good pool closing kit.
    Good closing kit, has always worked well for us.
  • Clear results
    This is the second season that we purchased this product. When we opened the pool last spring, the water was so clear. We were so impressed! This was the first product that gave us outstanding results. Very easy to use.
  • 3rd time buying this closing package, Great product
    This is my third year purchasing this closing kit for my 18 foot round above ground pool. It’s very handy and everything comes all in one delivery so you don’t have to worry about anything else besides the proper steps closing for the winter. When done properly it keeps the pool, sparkling, clean all winter, which makes for a very easy opening in the spring.
  • Easy and effective
    Everything you need in one kit. Just put it in my above ground pool for the third year. Each spring I’ve opened the pool to clear water that is easy to bring up to speed for the season. Very happy with this product
  • For all your pool needs
    I have purchased In the Swim products for years and they have outstanding products. Easy to use, easy to understand.
