Just about everything that is added to the pool water will change the pH. And anything that exits or is carried out of the water changes the pH. Even the type of pool wall surface will affect the pH.
Our Pool & Spa Operator Handbook lists a few things that affect the pH:
- the bathers
- the disinfectants we use
- the source water
- air-borne debris
- the water balance chemicals that we use
- aeration and evaporation.
In our CPO certification class this past Thursday and Friday, July 21-22, at PoolCorp’s Superior Pool Products building in Anaheim, I stressed that we should know the pH of every chemical that we put into the pool, so we can predict the direction of pH change in the water. The chart above is from a page out of our class Handout Packet showing the pH of common pool water chemicals. TIP: download this chart and put it in your truck — it’s good to keep it handy as a quick reference.
Our stay in Anaheim during our class this past Thursday and Friday was especially enjoyable. We recently entered a business agreement with Ayres Hotels of Southern California. They have offered a very special nightly rate to us and to our traveling students during our two-day CPO certification class. We were welcomed to the Ayres Hotel in Yorba Linda with a walk-though, complementary night stay and breakfast. For all future students traveling to our Anaheim CPO class, this is the place to stay! It’s just minutes from our classroom at PoolCorp’s Superior Pool Products building in Anaheim. Please click on the picture to the left to review their excellent accommodations.
Thanks, again, to Shelly Miller and crew AND a special thanks to the guys helping us carry our equipment and supplies upstairs!
