I’ve treated the pool for mustard algae but not 100% sure I’ve got it
My free calorie levels haven't change over night
Can I assume I’ve treated it ?

If you first passed the regular SLAM Process criteria, which include the Overnight Chlorine Loss Test, after that you then increased the FC to Mustard Algae levels for 24 hrs, then yes, you can assume you have eradicated the MA.
