Clorox Pool&Spa Winter Pool Ball for Swimming Pools

from jay

Excellent product. I've used it in the past and it kept my pool clear all winter. Could not find in store. Shipping cost was a bit high.

I've had a pool for several years now starting at a 14 ft and now ending with a 20 ft. Have tried all the kits and - always a job in the spring. Last year I bought the pool ball for closing and will use one again this year. It was amazing.

This product helps extend the life of the chlorine under the pool cover for the winter months. It helps to have crystal clear water when you take off the cover a lot.

This little ball is awesome. Every year we have gone out in the spring to a nasty green pool because the so called winterizing chemicals were not worth a pint of.....well you know! This year, I thought someone snuck over and cleaned the pool for us. Only parts that were really dirty are the sides...

Better than using ANY other combination of shock, chlorine etc. A Godsend especially during this shortage of pool chems since fires destroyed 2 major chemical companies
