I've been reading about the method for getting rid of mustard algae. From the different discussions here it appears you are supposed to bring your pool first to "slam" or shock level until you get a OCL test of less than 1ppm then raise to mustard shock level. I guess I'm curios why? Why not just get to mustard algae shock level and hold it there? Is the elevated shock level something that could harm a vinyl liner? I would think bringing to levels needed to kill the M.A. would be the starting point. I'm just trying to learn a bit more about the how and why of the things we do.
For example, My pool at
cya 40
ph 7.5
Bor 15
TA 150
Calls for a shock level of 16 but a mustard algea level of 24. So why not just go to 24, hold until you have the appropriate OCL and CC results and then let it come down to normal FC, do a PH reading and call it a day?
