The sera CO2-Start fertilizer system is easy to install and operate. It is ideal for the very widespread and popular smaller aquariums up to approx. 31.8 US gal. (120 liters). sera CO2-Start consists of an optically unobtrusive sera CO2 diffusion reactor and the correspond- ing sera CO2-Tabs plus. This convenient and uncomplicated CO2 fertilization sys- tem can be integrated into the aquarium even by beginners without any previous knowledge entirely without any problems.
