This is undoubtedly printed somewhere for easy reference, but I don't see it in Pool School, and the search engine won't look for 'shock,' as it's too common a word.
I understand pool shock is a process rather than one rise of chlorine, but how do I know when the process is completed? The only thing I can think of is to check for an absence of Combined Chlorine. (Note - I have a DPD chlorine tester, but not a FAS.)
Thanks.
