sera Co2 Start

Carbon dioxide (CO2) is the basic food of plants. In addition, the dosed addition allows the setting of a slightly acidic pH value, which is preferred by most plants and fish kept in aquariums.
The inexpensive, easy to install and use CO2 fertilization system sera CO2-Start is ideal for the very common and popular smaller aquariums up to approx. 120 liters.

sera CO2-Start consists of a very small, optically inconspicuous sera CO2 diffusion reactor that can be easily concealed by plants or decorations, as well as the corresponding sera CO2-Tabs plus.

This practical and uncomplicated CO2 fertilization system can be easily integrated into the aquarium and operated even by beginners without any prior knowledge.
