That’s my understanding too and I’ve seen the same.

Do you test for CYA levels? I think that’s what’s impacted most by repeated use of shock, if it has Trichlor or Dichlor in it. If what you’re using is just a concentrated chlorine, then it shouldn’t have an effect.

I've used a few different shocks, honestly whatever was in stock or on sale. I've seen differing schools of thought on shock. Most claim it has no impact other than the brief spike in chlorine. I am probably going to move to the Pinch A Penny gold liquid.

As far as CYA I check it every few months. Monthly through the summer. I've only had to add once last year. (we didn't get plaster until July 4th)

I suspect the rising PH is just a function of our water, water table, rain PH etc. On a side note, the twin bottles of acid I was buying from Home Depot went up from like $13 to $18. Ahh inflation.

Super cheap and very accurate. I used my Taylor and special CYA kit initially and pulled a strip and after a couple of months of identical results I now go with this..soooooooooo much easier to use. Dip in water, wait 15 seconds, read the colors.

Great way to keep an eye on CYA

7-IN-1 TEST STRIPS: Tests the most critical parameters: pH, Total Chlorine, Free Chlorine, Bromine, Alkalinity, Total Hardness, & Cyanuric Acid

AQUACHEK ACCURACY: Using medical industry technology, our test strips offer comparable accuracy to liquid tests; No measuring & counting drops of reagent, leaving less room for error
