Great explanation

[@nctae]

Very useful for my assignment thank you!

[@tedraver]

So if the test strip showa 0 total Chlorine and the free Chlorine says its in the ok range, thats ok?

Seems to me your test was faulty of thats the case. It should be impossible for total to be below free.

If it’s showing 0 total chlorine then you have no chlorine whatsoever in your water.
