"Yel/Mstrd Min" is 15% of the CYA level"
Ran across that in reading up on killing mustard algae, and I have no idea what it means or what it is worth. I understand the shock value of 60% of CYA value but have no idea what good the 15% minimum as referenced to mustard value represents. When would that be used and what for?
Related question: Why is it recommended to bring the pool to normal shock value for 24 hours before proceeding to the "upgraded" level for mustard algae? Why can't you just go straight to MAXIMUM!
