  • High Chlorine Consumption in the Pool: Why 20 Liters of Chlorine Disappeared in Two Weeks

    An almost empty swimming pool with some dirt on the bottom, a green hose, and a small pump. A staircase leads down to the pool, which is surrounded by light-colored tiles—factors that can affect chlorine usage when you’re preparing the pool for use. www.commaik.de

    Too much chlorine in the pool, a chlorine canister that’s constantly empty, or water parameters that don’t add up even though the water is clear: There are many possible causes for high chlorine consumption. In addition to sunlight, temperature, and swimming activity, the pH level, the chlorine products used, and cyanuric acid also play an important role. Even a good redox value does not automatically mean that the measured chlorine level in the pool is interpreted correctly. I noticed the problem after installing the BAYROL Automatic Cl-pH. In just under two weeks, the dosing system used about 20 liters of liquid chlorine—even though the water was clear and the system…

  • Installing the BAYROL Automatic Cl-pH in the Pool and Retrofitting a Temperature Sensor: My Experience

    An automatic BAYROL pool control unit, along with piping, hoses, valves, and sensors, is mounted on an OSB wood wall; the system features a digital display and a state-of-the-art water analysis system. www.commaik.de

    Having crystal-clear pool water shouldn’t depend on whether I have the time or inclination to read test strips and adjust the water levels manually. That’s exactly why I upgraded my pool system with an automatic dosing system and installed the BAYROL Automatic Cl-pH. The system continuously measures the pH and redox values and can dispense chlorine and pH adjusters as needed. In a second step, I retrofitted a BAYROL temperature sensor. This allows me to check not only the water parameters but also the current water temperature via the display, the web portal, and the app. In this field report, I document the installation and commissioning of Automatic Cl-pH, explain…
