The sera flore CO2 active reactor is integrated into an existing water circuit (e.g. external filter), or it can alternatively be operated with a pump. The rotors ensure strong blending of CO2 with the aquarium water, allowing to dissolve several hundred CO2 bubbles per minute.

The holder included with the kit allows attaching the reactor inside or outside the aquarium (e.g. in the cabinet), depending on the existing installation. The material color (smoky gray) is effective against algae settlement. Easy to clean.

Recommendation:

• sera flore CO2 active reactor 500 (up to 500 bubbles CO2/min): for aquariums ranging from 250 liters (66 US gal.) up to 600 liters (159 US gal.)
• sera flore CO2 active reactor 1000 (up to 1,000 bubbles CO2/min): for aquariums above 600 liters (159 US gal.) and densely planted aquariums
