Dennerle Carbo Bio Start — Natural Bio CO₂ System for Planted Aquariums
The Dennerle Carbo Bio Start is a complete bio CO₂ fertilization system designed to support strong, healthy plant growth in freshwater aquariums. Using biological CO₂ generation from renewable gel, it delivers a steady and natural supply of carbon — the most important nutrient for aquatic plants. This improves photosynthesis, promotes vibrant plant colours, and helps plants outcompete algae.
CO₂ production begins automatically within 24–48 hours after setup, making Carbo Bio Start an ideal solution for both new and established planted tanks.
