I just purchased a salfert and hanna alkalinity test kits. I figured I would start off using my salfert. Before I ran out of my old hanna fluid I was at around 6.8 dkh. Now before I take a fit and make an *** of myself I want to ask. Using my new salfert kit the water has to change from blue/green to an orange/red . Well after I finish adding the drops my water does not change from a light blue .
I've got nothing to measure. How do u read this?
