Hi all, I just got a new hanna dKH checker. I tested my new, lightly stocked reef and was surprised to get a reading of 6.2. This seemed extremely low to me so I tested it at least 7 times and got either 6.2 or 6.4. I then tested my new saltwater I made for a water change made with reef crystals and somehow got 5.8... somehow lower than my reef, so I tested that numerous times and keep getting the same result. Could I have gotten a bad tester?
