Apart from light, aquatic plants need nutrients, not only nitrogen, potassium, phosphate and trace elements, but also carbon, which is essential for life. This is supplied not only by carbon dioxide in the air, but also by CO2, which is produced and carried in natural waters by microorganisms. In our biotope in the living space, however, there is often a lack of CO2, which can usually be seen in the sparse growth.  

Plants with a good CO2 supply are vital and show a more intensive colours. Increased oxygen production benefits the fish, shrimps and snails - the aquarium ecosystem in the living space looks more attractive and is more stable.
