Healthy fish thanks to an ideal pH value

The acidity defines the pH value of the water. It needs to be constantly checked and adjusted as necessary to maintain the health of the fish and plants. The correct pH value depends on the fish stock of the aquarium. The wrong pH value can cause stress and disease.

Easy to connect

Connect the pH electrode with the BNC connection to its corresponding measuring and control device. – RELIABLE: The electrode has been individually tested and documented and needs to be replaced after about 2 years. It comes with a large protective cap, filled with storage solution.

pH electrodes:

Every pH control or measuring device and also the JBL pH-CO2 control unit (JBL PROFLORA CO2 CONTROL) requires a pH electrode (JBL PROFLORA CO2 SENSOR) to measure the pH value of the water. pH electrodes age with time and must be replaced about every 2 years. Every 30-45 days the pH electrode needs to be calibrated so that it continues to show accurate values. During calibration, the functionality of the electrode is also checked so that you know when a new electrode is needed. The pH electrodes do not like the addition of medication to the water and need to be placed in a glass of aquarium water during treatments.

Positioning the pH electrode in the aquarium:

Attach the pH electrode with the suction cups supplied ideally to a dark area in the aquarium with little current. Electrodes easily become algae-ridden in very bright locations.
