## Summary description

Compact pressure reducer designed for CO2 aquarium systems from sera flore. Provides regulated CO2 flow for planted aquaria; metal housing in silver. Intended to connect to CO2 cylinders and downstream tubing to ensure stable gas delivery for plant fertilization, dosing, and maintaining aquarium CO2 levels.

## Long description

The sera flore pressure reducer regulator for CO2 aquarium systems is a compact metal-bodied regulator in silver designed to connect to CO2 cylinders with an external valve and deliver a stable, reduced gas pressure for planted aquaria. Made in Germany, this unit reduces bottle pressure (approx. 50–60 bar) to aquarium-safe working pressures (approx. 0.1–2.5 bar) and includes an integrated fine adjustment valve to set the precise CO2 flow required for plant fertilization and stable CO2 dosing.
Advantages
The metal housing provides durable protection and a professional appearance while ensuring reliable performance in routine aquarium use. The integrated fine adjustment valve allows precise regulation of output pressure and flow, helping to maintain consistent CO2 levels. Compatibility with common external-valve CO2 cylinders simplifies installation and replacement, and the compact design minimizes space requirements near the gas source.
Suitable for (tasks / use cases)
Regulating CO2 delivery for planted freshwater aquariums
Precise CO2 dosing to support aquatic plant growth and photosynthesis
Connecting CO2 cylinders with external valves to tubing and downstream diffusers or reactors
Small to medium aquarium setups where space-saving regulators are preferred
Key specifications

How to use
Mount the pressure reducer onto a compatible CO2 cylinder with an external valve following the cylinder manufacturer’s instructions. Connect downstream tubing from the regulator outlet to your aquarium diffuser, reactor or dosing system. Open the cylinder valve slowly and adjust the fine adjustment valve to achieve the desired working pressure and CO2 flow. Monitor aquarium CO2 levels and plant response, and make small adjustments as needed to maintain stable conditions.
Usage recommendations
Use only with CO2 cylinders that have an external valve and ensure all connections are tight and leak-free. Check regulator and tubing periodically for wear or leaks. When adjusting pressure, make small incremental changes and allow time for the aquarium to equilibrate before further adjustments. Follow all safety instructions provided with CO2 cylinders and store cylinders upright in a secure location.
