How many sera CO2-Tabs plus per day are required? How does the system exactly work? After all, the tablet dissolves rather quickly. Hello, this, of course, basically depends on the plants you keep (species, number, size) and the other growth parameters (light, minerals, temperature, conductivity, kind of bottom gravel, etc.), so it is never possible to predict precisely. A dosage recommendation related to aquarium size is included in the instruction leaflet of the sera CO2-Start system. Upon dissolution, the reactor contains a rather strongly concentrated CO2 solution. The CO2 then by and by difffuses through the special plastic of the reactor, thus ensuring continuous dosage.
