Help!!!!!!! I added 20 oz acid at 12:30 today to lower ph. Tested again at 5 and added another 6 oz. Per Pool Calculator, this should get my pH to 7.6. I was heading to store for more bleach (for mustard algae shock) and decided to test TA so I could pick up some baking soda too. I thought my TA was 48 on 7/31. I just tested (6pm) and TA is basically off the chart on the high side. I used K-2006 kit and tried using the regular test of filling tube to 25 ml. I quickly realized that I was putting in too many drops trying to turn water red so started off and used 10 ml sample. I quit after adding 22 drops of R-0009 and still hadn't turned sample red...it was green, then blue, then yellow and heading darker/to red but, YIKES, that is some high TA.
Do I lower pH to 7.2 and aerate pH to 7.6 then lower again???????
