I just filled my new pool. According to the manufacturer it holds 14364 gallons. After filling the pool I added 7 pounds of dry CYA and let it dissolve. According to pool math 7 pounds of stabilizer in 14364 gallons should put my CYA level at about 58. The directions on the product show numbers very close to what pool math predicted.
However, I just tested the CYA twice this morning with the taylor test kit and the first time I could see the dot at 90 and it had all but completely disappeared at 80. The second time I thought it was a bit more visible at 80, but it was completely gone at 70. I’m doing the test according to what I believe are the best practices - Outside on a sunny day with my back to the sun, so the reading is being done in the shade of my body. Holding the indicator at waist level and taking the reading quickly without staring at it too much.
Given the fact that this is all new water in the pool and that I’ve added a known amount of CYA I think it’s pretty likely that the level is actually pretty close to 60, but I’m a little concerned that I’m reading 70-80, so this makes me wonder if I’m doing something wrong as I read the test.
