Okay. For future testing though, please stick to the Taylor FAS-DPD (powder & drops) for accurate FC testing. As you now know, those strips are horrible. Definitely let the FC drop since you are currently 2Xs higher than recommended for your SLAM level as seen on the
FC/CYA Levels. Once it drops back to about 12, continue the
SLAM Process until you are sure you've passed ALL 3 SLAM criteria.
From there, after you pass the regular SLAM, if you still believe you have Mustard Algae, only then do you increase the FC to MA levels, and even then only for 24 hrs. Good luck!
