Hanna Calcium checker

mike007 · Oct 9, 2013

Everytime i test my calcium with this tester it shows something different. Comparing with Redsea test it shows my calcium level is about 175 ppm more. Has anyone had this problem?

Yes it is. Use the Hanna water that they produce. Saves a ton of headaches!
