Why all the effort. I oak my PH unit maybe twice a year. In nature, the PH value holds even for equipment and specifications. You can be sure that the fish it does not matter whether the PH is 5.1 or 5.5. In its habitat, the PH value changes safe after a rain in minutes without which he gets into trouble. Think that is intended to show a PH unit rather where Ph is acidic or alkaline, the value is in the aquarium anyway not stable and changes with changes of water and food.
