Healthy Fish Thanks to Optimal pH:
The acid content determines the pH of the water. To keep fish and plants healthy, this pH must be constantly monitored and adjusted to the existing conditions. A good pH depends on the fish population in the aquarium; an incorrect pH can cause stress and disease.

Easy connection:
The pH electrode is connected to the respective measuring or control device via the BNC connector. SAFETY: The electrode has been tested with an individual test report and should be replaced after approximately 2 years. It is equipped with a large protective cap filled with a preservative solution.

pH Electrodes:
Every pH measuring or control device (JBL PROFLORA CO2 CONTROL) requires an electrode (JBL PROFLORA CO2 SENSOR) to measure the water's pH. pH electrodes age over time and should be replaced approximately every 2 years. A pH electrode should be calibrated every 30 to 45 days to continue displaying accurate readings. Calibration also includes checking the electrode's functionality, which indicates whether a new electrode is needed. pH electrodes are sensitive to the addition of medications to the water and should be placed in a glass filled with aquarium water during treatment.

Positioning the electrode in the aquarium:
Install the pH electrode using the suction cups provided in a low-current, ideally dark area of ​​the aquarium. In very bright areas, the electrodes easily become covered with algae.
