Great product, perfect way to close down pool for the season, I have been using this since 2016, every year opening the pool, the water is clear and ready to go.

We used this last year and this year to close our family pool. It really simplifies the process and does the job great! One stop shop to get everything in one shot! Keeps the water quality good throughout the off season, algae growth down, and chlorine levels in check so you have a clear pool when you open the following season! No swamp water with this kit!

We have a 15x30 above ground pool. This is our second year purchasing this. Easy to do and follow directions. When opening the pool last year the water was crystal clear! To note we did not add the extra algaecide in March as the directions noted becuase the water was still clear. Super easy to open the pool. We will use this every year!

I know it's early, but summer will end soon! If you're like me and want a super easy, hassle free way to close your pool for the winter.. purchase this kit. It takes the guess work out and was the easiest thing to do. Opening my pool this year was crystal clear and I contribute it to the end of season kit. Definitely worth the purchase!

We've used this for years. It's fast, easy to use, and works very well. When we open the pool in the spring, the water is clean and it's just a matter of starting up the spring-fall chemicals, and we're ready to go! It's also easy to find in stores. You don't have to go a 'pool service' store, although they'll have it too. You'll be able to find it in most big box stores where pool chemicals and water floaties are sold.
