  • Great kit for a fair price !
Style: Kit Only Size: Deluxe
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 ! ... show more

  • Great value
Style: Kit Only Size: Super
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.

  • 3rd time buying this closing package, Great product
Style: Kit Only Size: Deluxe
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. ... show more

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
