My test kit arrived. I've drained half the water and refilled which successfully lowered the CYA from 100 to 49, but raised the TA to 130, according to the pool store test yesterday morning. Their recommendation was to add acid, which I had just drained half the water to reduce. But when I tested it with the new kit, the CYA was closer to 70, while the TA confirmed 130. Another extreme discrepancy was with the CH. According to pool store only 200, but according to my test, over 500! The test water was supposed to turn from red to blue, but after 50 drops, I settled for lilac. The chlorine test presented yet another question. How long does it take and how completely must the DPD powder for the chlorine test dissolve? First test for FC, where I didn't allow as much time for dissolution, was 2.2, and the 2nd test, when I allowed more time for dissolution, was 1.8. CC was 4.4, when the pool store analysis was 0. I have emailed Taylor for their input, but thought y'all might have some thoughts sooner. Why did I want a pool?? Thanks for any help.
