Professional use of pH electrodes for aquariums: liquid for the calibration of electrodes with pH 4.0
Healthy fish and plantsThe pH value defines the acidity of the water. It needs to be constantly checked and adjusted as necessary to maintain the health of the fish and plants. The right pH value depends on the fish stock of the aquarium. The wrong pH value can cause stress and diseases. Using an electrode the value can be precisely measured. Cleaning and care of electrodesBacteria, lime and other impurities which settle on the electrode can falsify the real pH value. The regular cleaning and calibration of the electrode ensure precise measurement and an unaltered pH value. Electrodes always need to be stored in a humid place.
