ok, i just went and rechecked it. you are right, i somehow mixed up the colors. it is TC 1 and bromine 2. looking at the bottle, i have no clue where the 6 even came from because it's not on any of the results, lol. the pH is still 6.8 and TA still 40. I bought some pH up yesterday, followed the instructions and for a 4,000 gallon pool i added 8oz and turned on the pump. and obviously it hasn't changed any of my levels. should i add more, if so how much?
