Side note. You lost a lot of FC before you closed because your FC was higher than normal maintenance level. At high levels it burns off faster.

I'm closed too. Did it last week.

Good to know. Is there a general rule of thumb or calculation that is done to give an expectation of how much chlorine is lost at a particular level?

Do a search in the deep end. Chem Geek might have posted something a while back.

I only had Calc 2, not even gonna try to figure it out. Too many factors, sunshine, CYA level, etc.
