Eheim CO2 SET400
Eheim CO2 SET400 – Reusable System with Night Shut-Off
Professional CO2 System for Healthy Aquatic Plants
The Eheim CO2 SET400 is a high-quality, reusable CO2 system designed to ensure strong plant growth, balanced water chemistry, and a healthier aquarium environment. Carbon dioxide (COâ‚‚) is one of the most important nutrients for aquarium plants, supporting photosynthesis and oxygen production while helping to stabilise pH levels. With stronger plants, algae growth is naturally reduced, creating a cleaner and more balanced ecosystem for your fish.
This set includes all essential accessories – from a precision pressure reducer with manometers to a CO₂ diffuser with bubble counter and safety features – making it a complete solution for planted aquariums.
Equipped with an integrated 230V magnetic valve (night shut-off), the system automatically stops COâ‚‚ supply during the night when plants no longer require it, saving gas and ensuring safe dosing.
