1. An aquarium pressurized gas vessel for supplying an aquarium (12) with CO2 gas generated in the aquarium pressurized gas vessel (10), wherein the aquarium pressurized gas vessel (10) comprises:
a receiving vessel (14) for receiving a nutrient substrate and a reactant interacting with the nutrient substrate such that the nutrient substrate and the reactant react with each other to generate CO2 gas;
a closing means (16) for closing the receiving vessel (14) in a pressure-tight manner;
a gas outflow device (18) for CO2 gas extraction from the aquarium pressurized gas vessel (10) for the aquarium (12), wherein the CO2 gas has a gassing pressure (p_B) when flowing into the gas outflow device (18); and
a continuously operating, permanently actuatable gas vessel pressure regulator (20) which is configured for adjusting and maintaining a gas vessel pressure (p_G) in such a way that it substantially corresponds to the gassing pressure (p_B).
