Total alkalinity is the estimate of all bases in the water and it is referred to as the buffering capacity of water. It is also regarded as the capability of water to resist change in pH. One of the most common and important bases is carbonate. Total alkalinity (TA) is expressed as mg/L or ppm of calcium carbonate (CaCO3). However, in the aquarium sector, TA is referred to as "carbonate hardness" or "KH," and it is often expressed as degrees (dKH) rather mg/L or ppm.

1 dKH = 17.9 mg/L or 17.9 ppm.

Waters with moderate to high levels of total alkalinity or total hardness  (50 ppm or greater) usually have a neutral to slightly basic pH. The pH of such water does not change throughout the day as carbonates and bicarbonates neutralize the carbon dioxide and other acids in the water. 

Total alkalinity is one of the most important parameters of water used for fish keeping or fish farming. In any form of aquaculture systems, alkalinity should be maintained at a higher level to avoid frequent changes in the water pH and other variables. Most of the time availability of inorganic carbon for photosynthesis tends to increase with greater alkalinity. However, higher alkalinity water is better buffered against pH change than are lower alkalinity waters. Alkalinity needs to be measured frequently in ponds, recirculatory systems, biofloc systems as well as in aquarium systems. Improper hardness and alkalinity may lead to acute to chronic stress responses in fishes. Fluctuation of alkalinity may also need to the disturbance in the osmoregulation processes of aquatic organisms. 

As alkalinity is an important water quality parameter in aquaculture systems, and it must be monitored and adjusted through liming and other management measures.
