    Love it!

    I've used it for 2 years now. It takes the guesswork out—just throw them in, close the pool, and you're set until next summer.

    Cleaner when we opened

    Used these last year when we closed our pool. Opening this summer was much easier, and the water was cleaner than it had been in the past.

    Very easy to use

    Very easy to use. Just pop the caps off and place them in your pool. No need to run your filter—just cover your pool.

    Great for pool closing

    Used it to close my pool last year and when I took off the cover the water was still fresh and ready to use.

    We used these last year when closing the pool. When we opened it up this year it was much cleaner than normal.

    Worth adding to the closing routine

    It was easy to add to my normal pool closing routine and didn't require a complicated process.

    I haven't used it through the full winter season yet, but the setup was straightforward and easy to understand.
