Kickstart Your CO2 Fertilization Journey

Carbon dioxide (CO2) serves as a fundamental nutrient for plants and helps maintain a slightly acidic pH level, which many aquatic plants and fish thrive in.

The sera CO2-Start fertilization system is designed for easy setup and use. It's perfect for the widely used smaller aquariums, accommodating up to approximately 120 liters (31.8 US gal.). The sera CO2-Start includes a discreet sera CO2 diffusion reactor along with the necessary sera CO2-Tabs plus.

This user-friendly and straightforward CO2 fertilization system can be seamlessly integrated into your aquarium, making it accessible for beginners with no prior experience.
