Supplementing CO2 via a DIY or Pressurized system will have an effect on water parameters and can lead to trouble if you are not prepared. This video highlights the main reaction of CO2 mixing with water and how pH plays a role in the conversion of CO2 into the different forms of dissolved inorganic carbon (DIC). • When CO2 is supplemented in the planted aquarium, the initial effect is drop in pH due to the formation and quick disassociation of protons from carbonic acid, the compound that forms as a result of CO2+H2O. The resulting compound is bicarbonate, an intermediate molecule in the DIC equilibrium. For aquariums with a neutral pH ~7 this will be the predominant form of carbon that results from the CO2 supplementation. • Bicarbonate acts as a pH buffer and helps to regulate the severity of pH swings that occur during different parts of the day and night in the aquarium. Carbonate is the final piece of the puzzle, but is rarely seen in high quantities in the freshwater environment. Carbonate formation will only occur at a high pH, generally ~8.5 and above. This compound often precipitates out of solution when in the presence of high Ca2+ levels.
