Sodium hydrogen carbonate is the major component of additives used for increasing alkalinity. It can be used by itself to increase the alkalinity of a marine aquarium. If dosed by itself, it will cause a temporary decrease in pH. However, this effect is short lived and the pH will rise back up to the equilibrium level after a couple of hours. Also called Sodium Bicarbonate.

Alternative source for this material than the commercially available alkalinity additives / buffers is Baking Soda or Bicarb Soda, both of which consist of sodium hydrogen carbonate.
