## Summary description

Sera FLORE Active Reactor 500 (MPN 007341) is an aquarium CO2 reactor designed to improve CO2 dissolution and distribution in planted tanks. It connects to external filters or pumps to enhance gas exchange, helping aquatic plants absorb carbon dioxide efficiently. Suitable for hobby planted aquaria where stable CO2 dosing and even distribution are required.

## Long description

Sera FLORE Active Reactor 500 is a CO2 reactor designed to improve dissolution and distribution of carbon dioxide in planted aquaria. The device is intended for connection to external filters or pump outlets and facilitates transfer of CO2 into the water column, supporting stable CO2 levels and more uniform distribution throughout the tank. The compact inline design is made to integrate with existing circulation equipment and reduce CO2 loss to the surface.
Advantages
The reactor increases the efficiency of CO2 dissolution by prolonging contact time between gas and water and by creating fine bubbles or increased mixing, depending on installation. It is suitable for continuous operation with external filtration systems and reduces visible CO2 oversaturation at the surface. The unit is built to fit common plumbing connections used in aquarium setups and is compatible with standard external pump flows in small to medium planted tanks.
Suitable for
 Planted freshwater aquaria requiring stable CO2 dosing
 Setups with external canister filters or inline pumps
 Tanks where even CO2 distribution and reduced surface loss are needed
 Hobbyist systems aiming to improve plant growth and prevent CO2 gradients
Key specifications
 Inline CO2 reactor for connection to external filter or pump outlets
 Designed for small to medium planted aquaria
 Improves gas exchange and CO2 dissolution into the water column
 Compact footprint for integration with existing circulation equipment
 Operates continuously with external filtration flow
How to use
Install the reactor in the return line of an external filter or after an inline pump so that water flows through the reactor body. Connect CO2 supply to the reactor according to the manufacturer's connection points, ensuring secure fittings and leak-free joints. Adjust the external CO2 regulator and bubble count to the aquarium's plant load, then monitor CO2 levels with appropriate testing methods. Regularly inspect connections and clean the reactor as required to maintain flow and gas exchange efficiency.
Usage recommendations
Use the reactor in systems with stable external flow and matched pump capacity. Monitor aquarium CO2 concentration and plant response after installation; avoid abrupt changes in CO2 dosing. Periodic cleaning of the reactor and checking of seals will maintain performance and longevity.
