    • 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

Style: Kit Only Size: Deluxe
We have been using this kit annually for several years and always have sparkling clear water when we open the pool in the spring. We've had an above ground pool for more than 15 years and mainly use In the Swim products. The quality for the price can't be beat.

Great pool closing kit at a very affordable year end price. Has everything required to ensure your pool is clear and not green when you open it up. I have been using this kit for many years and it never let me down.
