I started a SLAM but I was also checking CYA during it. At one point it raised so I entered that into the app. Then I read somewhere on here, I guess a forum post, that said to just use the original CYA number prior to the SLAM. Which is correct? I am still SLAMMING currently and need to know if I'm wasting my time using the original CYA reading. However, once I read that post, I haven't checked the CYA again.
Test for and adjust for CYA changes during SLAM?

It’s a good idea to check your CYA periodically during the SLAM. If you backwash the filters you lose water and CYA can drop over time. If you added CYA at the start, it can take a few days for it to register on the test, and it’s good to verify what you actually added.
