CO2 bottle for aquarium - the most important things at a glance

CO2 bottles or carbon dioxide systems are of great importance for every aquarium. They support plant growth in aquariums as they supply the plants with enough CO2 to carry out photosynthesis effectively. There are different sizes of CO2 cylinders on the market, common are 500g, 2kg and even 10kg units, which can be selected according to the size and needs of the aquarium. Differences between the products lie in the filling capacity, the material (steel or aluminium), the pressure regulator and the filling process (disposable or refillable). Some systems have an integrated pressure regulator that allows the CO2 pressure to be adjusted and thus the CO2 supply to be regulated. When buying, make sure that the bottle is TÜV-tested and has a level indicator, a check valve and, ideally, a night shut-off to avoid overdosing on CO2.
