Cavitation
Cavitation is surface damage that occurs often in improperly-sized swimming pool equipment, where the water is pumped at pressures and velocities beyond limits, creating damaging high and low pressures.

Cationic Sanitation
Cationic sanitation is a method of cleaning a swimming pool by use of a cationic surfactant, which makes water wetter and enables sanitation products for pools reach small crevices where microbes can grow.
-
Carbonate Alkalinity
Carbonate alkalinity represents the amount of carbonate ions present in water, and can be indirectly determined in swimming pool water by measuring the water calcium hardness level.
-
Calibration
Calibration is a term to describe testing and adjusting the results of a device to a known quantity, resulting in accurate test results.
-
Calcium Indicator Reagent
A calcium indicator reagent is used while performing a calcium hardness test on swimming pool water, and is responsible for turning a water sample a red color.
-
Calcium Buffer Reagent
A calcium buffer reagent is used during swimming pool water tests to determine the calcium hardness level of the water.
-
Biguanide
Biguanide is a type of swimming pool sanitizer that can be used instead of chemical-based sanitizers like chlorine or bromine.
-
Base Demand
Base demand is a term used to explain the extent swimming pool water needs a basic substance added to increase the pH level.
-
Base Demand Test
A base demand test measures base demand, determining the extent an alkaline substance needs to be added to pool water to increase the pH.
-
Acid Demand Test
An acid demand test determines how much acid is required to decrease the swimming pool water pH level.
