Recently our Customer Experience Team has been getting several inquiries regarding pH drift. Of course, our first question is “what is your alkalinity reading”? As we have discussed in previous editions of Rick’s Remedies alkalinity “sooths” pH to keep it from going all over the place! When we ask this question, the answer is typically, “well, it is right in range between 80-120””… perfect right? No, not always!  What we measure is Total Alkalinity with our test kits. Total alkalinity is the sum of Cyanurate Alkalinity and Carbonate Alkalinity. High stabilizer levels (The Protector) can affect our Carbonate Alkalinity which we can refer to as “Adjusted Alkalinity”.   

Ricks rule of Thumb: for every 100ppm of stabilizer deduct 30ppm of alkalinity from your alkalinity reading on your test strip.

Here’s a quick example:

Measured alkalinity 120 ppm

Measured Stabilizer 200 ppm

Adjusted alkalinity = 120-60

As you can see in this example Adjusted Alkalinity is 60 ppm, this puts us out of the recommended alkalinity range of 80 ppm-120 ppm, which can make our pH difficult to control.

Here are a few other things to consider:

  • High stabilizer levels are caused by stabilized sanitizers such as Trichlor (3 inch tabs) or Dichlor (granular shock from big box stores) to reduce the amounts of stabilizer introduced to your pool consider liquid shock or calhypo shock.
  • Read your test strip instructions to make sure you are letting them process the correct amount of time before doing your visual reading.
  • Make sure your test strips are stored in a cool place
  • Check the expiration date on your strips to make sure they are fresh

Enjoy your pool!

  • “Just wanted to thank you for a great product. After four weeks of trying several different products and also adding way to much chlorine, we can finally see the bottom of our pool. Added Revive! at 6PM last night, by the time we went to bed, we could notice a difference and when I got up this morning everything had settled to the bottom. Used the vacuum for about an hour this morning and were swimming this afternoon. Will probably have to vacuum once more, but so glad this product was recommended to us.”

  • “Easy, simple, worry free…these all describe how my pool maintenance has been since I started using EZ POOL! I have a big pool and it is not a big job with E-Z POOL, just once a week. Once the pool is open and clear in the spring, I just have Caryl’s experts test my pool sample once a week to make sure the balancing chemicals and pH are good. Algaecides are not needed. Brush, brush, brush, as Caryl recommends and my pool is beautiful all summer! Also, it is gentle to the skin and does not effect your hair color. I highly recommend E-Z POOL!”

  • “I have used the EZ Spa now for four years. It is the best spa treatment I have ever used. It makes the water feel really soft and refreshing. I use it once a week and forget it. My spa stays crystal clear. I love this stuff. Not to mention when you use EZ Spa you don’t have to buy so many other chemicals. I also noticed that EZ Spa is extremely gentle on the skin. I can’t say enough about how good this stuff is. Try it, you’ll love it!”
