Aquatic plants benefit greatly from carbon fertilization in the aquarium. For this purpose, a CO2 system is used.

Carbon is one of the most crucial nutrients for aquatic plants. It is added to the tank water primarily by the injection of gaseous carbon dioxide (CO2). Lush plant growth is relatively hard to achieve without an additional CO2 supply, especially when it comes to the more demanding plants used in aquascaping.

CO2 can be supplied via a pressured gas system or via a biological CO2 supplying system, in which the gas is produced by yeast fermenting sugar. If you want to use a pressurized gas system, make sure it is equipped with a high-quality pressure regulator and a reliable needle valve.
