CO2 bottle

The CO2 Necessary for the Growth of Corals

The CO2 Bottle has several applications in aquariophilia. In freshwater, carbon dioxide is dissolved in the aquarium water, which will promote the good health and growth of plants. However, be cautious as this gas acidifies the water and, in excess, can be harmful to the respiration of fish. The CO2 Bottle in saltwater is specifically used to acidify the water to dissolve aragonite or another calcareous substrate in the reactor, thereby providing the calcium necessary for the growth of hard corals.
