I bought a HTH 6 test kit at Walmart. They did not have a K2006. I should have mentioned earlier that I have issues with my local pool stores. Both of them have always steered me to the highest price solutions to any problems I've had. For example, I used their acid reducer for the first few years of pool ownership, until one year, they were out of it. As I left the store, one of their techs caught me and told me to go to my local Ace to get a gallon of muriatic acid. I was so upset by this deception that now I only will go to them as a last resort. Anyway, I've used HTH products in the past with no problems, so I have faith this is also a good product. I'm guessing someone makes it for HTH.
I tested again this morning with the same results; PH at 7.2, TA of 80, hardness of 210. Bad news is my CA is almost 0. I added the recommended amount of stabilizer and will test that again tomorrow. My pool water is crystal clear, very cold, and has some very stubborn green and black algae clinging to the vinyl.
