I can't seem to get an accurate reading for the calcium hardness. I keep seeing purple!
Tne first time I ignored the purple and counted drops till it turned blue. That gave me a reading of 525!
Then I tried the distilled water suggestion and only got 18.
What am I doing wrong? Could my well water have anything to do with it?
