BIO-CO2: Bio Co2 is a microbial carbon source. It allows aquarium plants an improved nutrient uptake and promotes plant growth and colourfulness of freshwater plants. 100 % BIOLOGICAL: The beneficial bacteria contained produce CO2 available for plants from the humic acid also contained in a biological process. IN COMBINATION: We recommend Bio-CO2 in combination with our plant fertiliser series. This provides plants in any freshwater aquarium with all the nutrients they need.
