In The Swim Pool Closing Kit - Winterizing Chemicals for Above Ground and In-Ground Pools - Up to 15,000 Gallons

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 !

Second year using this. Had no issues at opening last year and the pool is still crystal clear when I check it.

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.

so far everything going smooth easily to apply

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.

First year I used this kit I opened up to a perfectly clear pool. Re ordered and used again this year! Will continue to buy

I've bought this for the last two years to close up my saltwater pool. It works great, water is crystal clear amen we take the cover of in the spring! Definitely recommend! Our pool is 28' round.

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.
