I am using the TH-100 test kit and trying to follow the instructions on The Extended Test Kit Direction Post for the DPD test. I have the following questions:
I seem to have no test cell with a 9ml mark. Am I missing something? Do I just use one of the cells and guess by getting close to the 10ml mark?
What is the test cell marked "Chlorine Only" used for?
The only color chart I can find in the kit is on rectangular cell included with the Basic Kit. Is this the proper chart to use?
