Ordered the TF100 last week and found it very simple to use. The question I have is with the combined chlorine. The page that compares the test kits says that the TF and taylor can detect CC as low as .2. How is this possible when you can only add one drop of reagent and multiplying by .5? So far I've tested it twice and have only had to add one drop CC = .5. Am I only to shock the pool when it is greater than .5?
The other question is of calcium hardness. The solution never turned blue. I was up to 60 drops befored I figured I did something wrong.
Here are the results from the TF100 and the color q tester.
I was questioning whether my color q was reading properly so i bought the TF 100 to double check it I am confident that my color q is fairly accurate other than pH. I am beginning to believe pool store tests were not accurate at all.
I am ready to begin BBB don't know if this is the proper forum for this question. Am I close enough on TA to add borax? I've been working at lowering it from close to 300 and have it down to 110.
Thanks for all of your advice so far. I'm looking forward to beginning the BBB pool program.
