Hi all, New spa and I used the TFT 100 CH test for the first time, I am a pool owner and am familiar with the TFT 100. I added 20 drops of R-10 and 5 drops of the R11L, the sample didn't turn red just a faint pink tint. I added one drop at a time of R12 and the sample turned to a faint blue tint. ran the test 2 time with the same result. when I do the TA test the colors are much darker.
Also starting from zero I added calcium for a target of 120 and my test result was 70 6 hours later. do I need to wait longer for the CH level to show?
