I read where you were saving reagents by not testing over 12ppm. If I we're you, I'd order more so you don't run out for the rest of the season. Don't worry about OCLT either until the green is gone and the pool clears more. I'd rather sleep a little more at this point.
Got some loaded in my Amazon cart waiting on payday. I have a prime membership so worse case is two day shipping. I'm watching it closely though...
