Do I need to use both balls?

Yes. Use both balls as one complete pool closing kit. One set treats up to 38,000 gallons and is suitable for medium and large residential pools.

Do I need to mix or measure anything?

No. This drop-in pool winterizing kit requires no mixing or measuring. Remove the plugs, place both balls opening-side down, then cover the pool.

Can I use this in a saltwater pool?

Yes. The Pool Closing Kit works with saltwater and chlorine pools, including above-ground and inground pools.

Does this replace my normal pool closing routine?

No. Complete your normal pool closing prep first, then add both balls before covering the pool. It helps support off-season water care and easier spring opening.

Will it help keep the pool clear over winter?

It is designed to help maintain water clarity and reduce off-season buildup, helping make spring pool opening easier. Results can vary by pool conditions.
