Regarding the calcium. I wasn't sure if the test was right. It really didn't turn red on the first part. Only a light pink and then no blue on the second part. So I figured I did something wrong.
Nope, it turns from pink to sky blue.
If your calcium is high and you have a Taylor kit then read the small print at the bottom of the calcium test section on the lid where it tell you how to do the test with a 10 ml sample so each drop of titrant equals 25 ppm calcium hardness. It does not have as much precision but if your calcium is around 400 ppm or higher it's all the precision you really need.
Just to make it esier (even though these instructions are printed inside the lid of the blue box) use
10 ML sample of pool water (instead of 25 ml)
10 drops of R-0010 (instead of 20)
3 drops of R-0011 (instead of 5)
then every drop of R-0012 equals 25 ppm of calcium hardness (instead of 10 ppm)
This page on the Taylor website has a lot of educational videos on how to do the various tests. You might find it useful.
