Review on 🔬 Comprehensive Salifert Alkalinity Calcium Magnesium Combo Test Kit: Accurate and Convenient Analysis for Your Aquarium Water by Eddie Tyson

I like these Salifert test kits. The results appear to be relatively accurate and they all work in the same way. I use them in the same order each time; Mag first, then Alk, then Calc to make the steps easy to remember. I think they are much more reliable than the cheaper tube test kits which require different steps for each test. These are just easier.
