Salt System newbie

[BigTallGuy]

In the infamous words of Gomer Pyle....Well Gooooolllleeeeeeee. I tested My pH and found that it had gone from 7.6 or 7.7 back up to 7.8 or 7.9 in about 1 weeks time. I added Acid and brought it back down to 7.4. So it looks like I'm going to need more Stabilzer. I had my stabilizer level tested again, it kind of blew me away at what the guy did. He filled the test cylinder with my water and added the solution, then he slowly pumped the spoon a couple of times, no more than three, and proudly announced that I had no stabilizer in my pool and then tried to sell me a bottle of CYA. I won't even mention what the results were, as I totally discount this an an accurate test.

So to re-cap, As Chlorine is depleted by UV rays or time or whatever, it does some kind of funky chemical wizardry and burns off the acid or maybe it leaves some sort of alkaline behind. In any case, the pH goes up. The Cyanuric Acid slows down this depletion of Chlorine, and there by slows or stops the pH rise. So, is this process unique to Salt system pools? As I stated before, I never really had to add acid before with traditional chlorine. So did the BTDG get this registered correctly in the old gray matter?

Don't worry Chem Geek, your job is safe, but thanks for your wisdom.
