Chemical test kits have limited accuracy and resolution since they rely upon the human eye to discern differences in color. Professional instrumentation incorporates a light source such as an LED or tungsten lamp with a filter and a light sensing detector to precisely determine absorbance and ion concentration. This level of instrumentation also offers greater resolution and accuracy, but can cost hundreds of dollars.

In saltwater systems, alkalinity is present in two main forms; carbonate (CO32-) and bicarbonate (HCO3-). Alkalinity is a critical parameter to check for in aquaculture, especially in reef aquariums where drastic pH swings would be catastrophic to corals. Further, alkalinity is important to the calcification of corals. The ideal range for alkalinity in reef aquariums is between 125-200ppm of calcium carbonate (7-11 dKH). Many test kits are available on the market that rely on a color change that needs to be judged by eye.

Many aquarists set up a regular supplementation schedule to maintain proper calcium levels. However, regular calcium monitoring is crucial to a healthy reef aquarium, even if such a system is in place.
