Sera CO2 Start

Getting started with CO2 fertilization is simple! Carbon dioxide (CO2) serves as a fundamental nutrient for plants and helps maintain a slightly acidic pH level, which is favored by many aquatic plants and fish. The sera CO2-Start fertilization system is designed for ease of installation and use. It's perfect for popular smaller aquariums up to around 120 liters (31.8 US gal.). The sera CO2-Start includes a visually unobtrusive sera CO2 diffusion reactor along with the compatible sera CO2-Tabs plus. This user-friendly CO2 fertilization system can be seamlessly integrated into your aquarium, making it accessible for beginners even without prior experience.
