I have the TF 100 Test kit. I am getting the hang of it now, but there is still one aspect to the instructions that is very confusing. It is under the Calcium Hardness Test section. The last sentence in step #2 says “Red indicates the presence of Calciumâ€. My first question is what does pink mean? It never turns red.
More importantly, my second question is, in step #3 at the end it says NOTE: If the pool water contains copper, add two drops of R-0012 prior to adding R-0011L and continue…
How do I know if my water contains copper? Why does the kit mention the Calcium point if it doesn’t go on to explain the significance of Calcium?
The only thing I can think of is either Copper or Calcium is a misprint and it is supposed to be the same word??
Thanks!
