    Testing water before installing softener. At 15 drops sample changed blue. After about 10 seconds it changed back to pink. Each drop added after that resulted in same result. Blue, then back to pink after a 10 seconds or so. Stayed blue at 20 drops. Swirled after each drop added. So what is my hardness?

    20 gpg. Sounds like you didn't mix it well enough.
