Video was on testing TA. I have no issues with TA test and as of a few days ago it was 60. I have not tried to move it up much for fear of moving PH up from 7.0 while trying to get chlorine up and water balanced. The calcium hardness test was the one in which I could not get to turn red ( kit says it will turn red if calcium hardness present) after adding the 5 drops of R0011. The 80/80 represents the calcium hardness - 8 drops of R0012 to turn sample from purple to blue.
