Are there any methods to test CYA outside of using the "drop test" method with the black dot? I am struggling with it as it seems pretty subjective.
About a month ago I accidentally dumped some stabilizer in my pool instead of calcium hardness increaser. I was pretty upset over it and my CYA bumped up to about 100 per my TFP test kit; the pool store's ALEX testing system came up with about the same number. I drained a little water from the pool and filled via our well. We've had a ton of rain over the past two weeks and the water level is really high. When I tested over the weekend the CYA seemed to be down to at least 80 possibly as low as the 65. However, I'm a little skeptical of the results as I just don't feel very confident around exactly when the dot disappears.
