What is rule for making other adjustments while slamming?

Currently TA =50 and pH is high. I also have a CH=100. I have not added anything at this point while slamming. Just wondering if I can or should attack more than one thing at once. Thanks.

  • The high chlorine during SLAM reacts or invalidates the other reagents
    • Phenol Red (PH reagent) reacts with high FC, causing a "false" high PH reading
      • it is not safe to "treat" (aka lower) PH when a FC reading over 10
      • ......so if you are in SLAM with a PH reading of 6.8, that's concerning, anything between 7.2-8.2 is "expected"/normal
        • if you get a PH 6.8 reading during SLAM, allow the FC to lower under 10, retest PH & TA, before continuing SLAM
    • Several of the other dyes will be bleached out by high FC, causing invalid readings
