pH Controller sera Seramic SE-08005 for CO2 systems (aquarium pH regulation)

sera Seramic SE-08005 for CO2 systems is a compact pH controller designed to monitor and regulate aquarium water acidity as part of CO2 dosing setups. The device measures pH and communicates with CO2 solenoid valves or dosing systems to help maintain a setpoint, supporting stable water chemistry for planted aquaria and community tanks. It is intended for integration into existing CO2 control loops and routine aquarium maintenance to reduce pH fluctuations.

Advantages

The controller provides continuous pH monitoring with direct interface to CO2 dosing equipment, enabling automated adjustments to maintain target pH levels. Its compact design allows easy installation near reactors, CO2 cylinders, or aquarium cabinets. By reducing manual intervention it supports stable conditions for aquatic plants and fish and can contribute to more consistent growth and colouration in planted tanks.

Suitable for

• Planted freshwater aquariums with CO2 injection
• Community tanks where stable pH is important for fish health
• CO2 reactors and inline dosing systems integration
• Hobbyist and advanced aquarium setups requiring automated pH control

Key specifications

• Function: pH measurement and control for CO2 dosing systems
• Interface: control output compatible with CO2 solenoid valves and dosing equipment
• Installation: compact unit suitable for mounting in aquarium cabinets or near CO2 systems
• Operation: continuous monitoring to maintain user-set pH setpoint

How to use

Mount the pH controller in a dry, accessible location near the CO2 cylinder, solenoid valve or reactor, following local electrical safety practices. Connect the controller’s output to the CO2 solenoid or dosing device according to the manufacturer’s interface requirements. Calibrate the pH probe if supplied, and set the desired pH setpoint appropriate for the aquarium inhabitants and plants. Observe initial operation to ensure the controller switches CO2 on and off as needed and adjust setpoint or hysteresis settings if available to prevent rapid cycling.

Usage recommendations

Regularly calibrate the pH probe and perform routine maintenance on the CO2 system; monitor readings after any changes to livestock, substrate, or fertilization. Use gradual setpoint adjustments and allow the aquarium to stabilise between changes to avoid stressing plants and animals.
