You're telling me! It's a State law. It says that "The following shall be measured in each spa or tub at least hourly during the hours of operation: Disinfectant levels, pH, Temperature and should be within designated range or adjusted accordingly."
Of course, Alkalinity and Hardness only need to be tested weekly.
I have a few calls around to places with hot tubs, but most are part of larger pools etc and they may very well just have someone there testing the water. I was hoping that there was some electronic device that would log the info electronically. Or even an electronic tester of any kind.
