Dennerle Carbo Bio Style 120 Refill – Reliable CO₂ Supply for Small Planted Aquariums

Dennerle Carbo Bio Style 120 Refill is specifically formulated to replenish the biological CO₂ production system used in the Carbo Bio Style 120. Carbon dioxide is one of the most important nutrients for aquarium plants, directly influencing photosynthesis, growth rate, and overall plant health.

This refill pack contains the required components to restart the natural fermentation process, producing a continuous and gentle CO₂ supply suitable for nano and small planted aquariums. It is an excellent solution for aquarists seeking an affordable and low-maintenance alternative to pressurised CO₂ systems.
