Alkalinity – What Is It and How Is It Controlled?

This is not a complete scientific discussion or description of alkalinity. It is simply intended as a base, as there isn’t a requirement for an aquarist to be a scientist and understand all. A basic understanding allows the aquarist to ensure the seawater in his/her aquarium is at the parameter desired and why.

Right, that said, alkalinity then. Alkalinity of seawater is the ability of the seawater to resist certain change. Alkalinity can also be called Carbonate Hardness. Seawater is on the alkaline side of neutral. To quickly describe this, pH is measured on a scale of 0 to 14, with 7 being neutral. Above 7 is into the alkaline side, below 7 is into the acidic side. Aquarium seawater is, generally, maintained between 8.0 and 8.4. So, as can be seen aquarium seawater is on the alkaline side.
