The other day I tested all my levels with the K-2006 test kit. All levels were in range except for my calcium hardness, it was at 70 ppm. I follow the info in the "How do I Use Chlorine in my hot tub" thread. After adding some calcium increaser to obtain the 130 - 150 ppm as recommended, the next day I tested and the level was at 190 ppm. Is this level to high? Should I try to lower it? Thanks in advance for the advice/Info.

In your manual, there should be a range of acceptable CH levels. You can Google the manual if you don't have it. For my premium leisure spa the CH range is 150-400. You should be okay
