  • Pool Closing Made Easy — Works Like a Charm!
Size: 30,000gal
The Summerbuddy Pool Closing Ball is a lifesaver for winter prep. Toss it in and forget it — no heavy lifting, no complicated setup, just simple protection that actually works. My pool came through the winter clean, clear, and hassle-free. It’s durable, easy to use, and way cheaper than dealing with green water and endless chemicals in the spring. Honestly, this little ball took a big headache off my shoulders. Total must-have for closing your pool the right way! ... show more

  • Best pool hack ever
Size: 30,000gal
This is the best thing I have ever bought for my pool. Was really skeptical but I'm glad I tried it. Put this in my pool last winter and covered the pool. Expected it to get nasty. Pool say covered with just this in it for almost 6 months and when I took the cover off my pool was still crystal clear. No algae, no foggy water just a clear blue pool. ... show more

  • Love these, so easy!!
Size: 30,000gal
Very easy to use, just toss it in the pool right before closing it for the winter. So much easier and healthier in the long run since it doesn’t take as much shock and such upon reopening your pool in spring! I also feel it’s better for the environment, as it allows for less chemicals to be used at the opening, which in turn saves you money!! It’s a win-win in my opinion! ... show more

  • Great Product for Closing Pools
Size: 30,000gal
I buy one of these pool closing balls every year when we close our pool. They help keep the water clarity clear through the winter. It is super easy to use and the directions are clear. Good value for your money.
