## Summary description

sera Seramic SE-08005 is a pH controller designed for CO2 systems in aquariums to monitor and regulate water acidity. The unit interfaces with CO2 dosing setups to maintain target pH levels, supporting stable conditions for aquatic plants and fish. It is intended for integration into aquarium CO2 control loops and routine aquarium maintenance.

## Long description

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.
