Q: Why should I get a 12-month (annual) chemical membership if I don’t use my pool/hot tub? A: It will help avoid your water going out of balance. Once it gets out of balance, it’s much harder and more expensive to get it back to where it needs to be. Q: What if I buy a 4-month chemical membership during the pool season and don’t use up all my months? A: Seasonal members that purchase pHin during the pool season can carry over any unused months to the next season. Q: What if I use my pool/hot tub for more than 4 months but less than 12 months? A: If you need more than 4 months, just renew for another 4 months. Use what you need this season, and the rest automatically rolls over to next season.  Questions? Find more answers.

Pool and Hot Tub Same Water

If your pool and hot tub share the same water using the same filter and pump, one pHin will do the job. Just select “Pools” in the cart.

Pool and Hot Tub Different Water

If your pool and hot tub don't share the same water, get 2 pHin Starter boxes: one for your pool and one for your hot tub.
