I just purchased my TF test kit and I'm glad I did. I took an initial test using the K-1000 for my PH and Chlorine. I also tested my CYA, which was very different then the readings the pool store gave me. I have a slight allergy growth on the walls of my pool, so my question is if I should SLAM it? for the most part the water is clear and the deep end is slightly cloudy. My Chlorine levels are at 2ppm and my CYA is about 70.
