Hi there,
Question on how to read the Taylor K-2006 test kit for Calcium Hardness.
We have well water and no softener. When I read the CH I'm getting about 120 - 140 for when the color goes from red to blue, but there's still pink floaters in it. When the spa company reads a sample they're in the 200 - 230 range. The instructions with the test kit say stop titrating when the color goes from red to blue overall and disregard any pink floaters. Does that mean there should be no pink floaters when you're done? If so, that seems to happen at the higher range, closer to what the store reads the CH as on their computer. And how blue is blue? It goes through a bit of a purplish phase at about 100 and then an extra 2 - 4 drops take it to what I'd call blue.
The other thought I had was the store print out is saying "Hardness" not "Total Hardness" so I assumed it's just CH but maybe I shouldn't. Is it possible they're reading TH and my test kit is reading CH and both are right? But I didn't think we cared about magnesium hardness in spas so I would think they're Hardness is CH only but it was just a thought I had.
thanks!
