Review on 🧪 Kh/Alk Test Kit for Carbonate Hardness and Alkalinity by Michelle Reitz

Like all titration tests, this test results in a color change in the water sample when the KH value is reached. However, it uses the syringe reading to tell you what the dKH is, not the number of drops. It's hard enough to get high accuracy on these titration tests without adding a second complication to make sure your syringe is properly filled. This overly complex approach to testing surprises me as Salifert's tests are usually simpler and very reliable. .
