The JBL Aquaristik and Terraristik Bio-CO2 Refill Set is an effective solution for supplying aquarium plants with carbon dioxide, an essential nutrient for growth. This set is suitable for aquariums with a volume of 30 to 80 liters and provides a continuous CO2 supply for up to 40 days. The application is straightforward: the two components A and B are mixed in a reaction container with water, activating a natural fermentation process that ensures CO2 production. This system does not require a CO2 pressure bottle, making it easier to handle and simplifying plant care. The Bio-CO2 Refill Set is thus a practical and environmentally friendly solution for aquarium owners who want to promote the growth of their plants while preventing algae formation.
