At that magic level, you need to hear the call to duty and shock it burn of the CC. To shock you pool properly, you need to be able to measure levels up in the 15 to 25 ppm of free chlorine. No test strip kit and very few drop based kits can do it either. You need an FAS/DPD type kit.

And you are referring to the real reason to test. Fecal matter is from my understanding the single most dangerous contaminant. You almost never hear about anyone ever having it. You could test it as if it were drinking water and get a coliform count. Most people get alarmed when the pool goes green with algae. It's not nice but it's not very dangerous in it's own right.

BUT

when algae can grow so can the dangerous bacteria.

and that's why we want accurate testing.
I apologize b/c I really don't understand your answer and don't know how or if to respond I have been a member for several years now and have Ben's complete kit and know exactly what my fc and cc are. I don't post to often b/c folks such as Watermom and Carl has vast more experience than I.
You are correct in regards to the strips and not knowing cc. If this is what someone is using I would probably suggest shocking weekly but would more so recommend buying Ben's kit.
