I have posted about my TA being high in a previous post and something about my testing puzzles me. I have said I cannot get my green reagent to turn red no matter how many drops of the ALK 2 reagent I use. Yesterday I used a small quantity of the sample from the pool, only one drop of ALK 1 reagent and after a few drops of ALK 2 got the desired red color change. I was more or less trying this just for sanity's sake. Could my TA be so high that the normal procedure would take a whole bottle of sulfuric acid to make the color change???? I am going to add acid tonight when I get home to bring the pH down and get everything under control. The water is clear and clean and the pH was 7.4 yesterday and the FC was 2. Not in dire straits as of yet. Was just curious as to if anyone else has had this problem with the TA test.
