The Aqua Medic pH Controller is a precision instrument for controlling the pH value in aquaria. In combination with a CO2 system and a solenoid valve the pH can be maintained at a constant level, and the CO2 supply to aquatic plants can be controlled. The unit is supplied with a large LED display and the control range is digitally adjustable from pH 3.5 to 10.5. The direction of adjustment can be set up or down. The Aqua Medic pH Controller has a BNC connection for pH electrodes (available separately).
The pH value is an electric value that is a parameter for the acidity of water. In the aquarium, the pH value together with the carbonate buffer system is of special interest.
In a fresh water aquarium, the pH value is responsible for the percentage of free CO2 that is used by green plants for photosynthesis. Fertilization with CO2 has been well-established for fresh water aquaria as base for a good plant growth. With the Aqua Medic pH Controller, the pH value can be adjusted to a given set point and kept constant by adding CO2 automatically.
In a saltwater aquarium, the pH value and CO2-addition are used in combination with a calcium reactor. The addition of CO2 into the calcium reactor is controlled by the Aqua Medic pH Controller. In addition, also Kalkwasser can be dispensed to increase the pH value after switching the control range.
