Top Questions

When is pHin going to begin shipping?

We started shipping pHin to our chlorine pool members in July and are working around the clock to get your pHin to you as quickly as possible. We will update you via email about when you can expect to receive your pHin.

This costs the same as just paying for chemicals alone, what's the catch?

We work directly with the chemical manufacturers to get wholesale prices, and we don’t have to pay rent for physical stores. We use the savings to give you great technology at great prices.

What will the price be for future years?

At this point we can't guarantee what our pricing will be for 2017, but we expect it to remain relatively similar to our 2016 regular price. Of course, we'll always try to reward our early preorder customers as much as we can.

Does pHin work with salt water pools?

Yes. Salt water pools usually require much more acid than fresh water pools, and you still need to monitor your chlorine levels - pHin takes care of both of those tasks for you, and even ships you what you need, whenever you need it! In addition salt water generators become ineffective when your water temperature drops below 60 degrees. pHin will monitor your water temperature, alert you if your water temperature drops, and automatically ship you any necessary chlorine.

My Hot Tub shares the same water as my pool, do I need two pHin Smart Monitors?

No. If they share the same pump and filter, one pHin will do the job.

How do pHin memberships work?

We currently offer two memberships: an annual membership that runs for 12 months, and a seasonal membership for 4 months (for those who drain or winterize their pool during the off-season). Seasonal members that purchase pHin during the pool season can carry over any unused months to the next season. For members that need more than 4 months, but less than an annual membership, you can simply add on extra months as needed at the discounted rate of $39/month. Please note that if you don’t winterize or drain your pool for the off-season, and you keep it open, just not heated or in use, then you should sign up for the annual membership, which will ensure that the chemicals stay balanced - once they get out of balance, it’s much harder and more expensive to get them back where they need to be.

What chemicals are included?

Chlorine (or Bromine for Hot Tubs), shock, pH increaser, and pH decreaser.

What about opening and closing my pool?

If you winterize your pool, we have two options for opening and closing your pool. You can simply tap on a button in our mobile app to have a service technician come to your house and open or close your pool; or if you prefer to do it yourself, we can send you opening and closing chemicals at a discounted price.
