sera guide - Splendid plants in your aquarium

11 Generally, CO2 is well soluble in water. How- ever, the gas must be specially dissolved in water for optimal solubility. So-called CO2 re- actors are especially designed for this pur- pose. Their low capacity to dissolve CO2 in water is the problem of many common reac- tors. The gas is not entirely dissolved, and CO2 gets to the water surface as a bubble, where it is lost for the aquarium. sera pro- vides different highly efficient reactors for in- stallation inside or outside the aquarium. 11 How is CO2 dissolved in water? Previously, using CO2 systems was mainly available for professional users. With sera CO2 systems it is possible also for aquarium hobbyists to provide their plants with CO2 easily, quickly and safely. Depending on the size of the kept aquariums and the plant den- sity, sera offers different CO2 fertilizing sys- tems. The sera CO2-Start set is ideally suited for small aquariums or few plants. It consists of the sera CO2 diffusion reactor and the sera CO2-Tabs plus. The tablet is put into the CO2 reactor and releases CO2 which is retained in the storage container of the reactor. CO2 passes the reactor walls only slowly and dis- solves in the water by and by without any losses. sera CO2 systems
