Dennerle Carbo Bio Depot 120 is the refill gel for the Dennerle Carbo Bio Style 120 CO2 fertilisation system, providing at least 40 days of consistent, biologically produced CO2 for your freshwater aquarium.
The CO2 Constant Gel is made from 100% renewable raw materials and reacts biologically to release a steady supply of carbon, the most important nutrient for healthy, strong plant growth and vibrant colours. Unlike powder-based CO2 products, the gel formula keeps output consistent throughout its full 40+ day lifespan rather than tailing off.
Simply swap in a fresh Carbo Bio Depot when your existing one runs out to keep your Bio Style 120 system topped up and your plants supplied with CO2.
Format: Dennerle Carbo Bio Depot 120, refill gel for the Carbo Bio Style 120 CO2 system, lasts at least 40 days.
