FAQ
QIs it normal for the winter ball to float vertically on the water surface?
A
It is normal. The winter ball is not meant to be dripped into the pootI directly; instead, it works through the circulation of liquid replacement. If you encounter this situation, there is no need to worry.
QWhat should l do if l receive a product with damaged packaging?
A
If you receive damaged products, please contact us via info@poolhacker.com, We will promptly arrange a replacement for you.
QDo you keep the filtration system running the winter ball?
A
No, keep the system off. I place the ball under the pool cover ffor winter and remove it in the spring. It works great

Overall rating: 4.6 / 5 from 17 reviews.
Love it! Ive used it for 2 years now it takes the guess work out just throw them in and close it up and you’re set until next summer
I used this last year and my pool was as clear as the day we closed it down. I’ve already ordered another one because they sell out fast! Just throw them in and cover it is all you do.
Used these last year when we closed our pool. Just opened and dropped them in our in ground pool. Opening this summer was much easier. Water was cleaner than it had been in past upon opening. Would definitely buy again.
Used it to close my pool last year and when I took off the cover the water was still fresh and ready to use. Will continue to use every time I close my pool for the year
We used these last year when closing the pool. When we opened it up this year it was much cleaner than normal. Will definitely use again. Highly recommended
