• Cyanuric Creep Cyanuric creep describes the tendency for the cyanuric acid level to rise over time in swimming pool water.
  • Cyanurate Alkalinity Cyanurate alkalinity represents the level of cyanuric acid present in swimming pool water, as cyanuric acid is used as a chlorine stabilizer in chlorinated outdoor swimming pools.
  • Copper Copper is a metal that can find its way into swimming pools with unbalanced water, resulting in metal pool equipment corroding and releasing copper into the pool water which can stain surfaces and leave the water a green-blue color.
  • Color Chart A color chart is often referred to when testing swimming pool water, and is often found in test kits and in test strip containers.
  • Chlorine Stabilizer A chlorine stabilizer refers to a chemical added to chlorine in manufacturing, or adding separately to swimming pool water to reduce the rate chlorine dissipates in water.
  • Chlorine Neutralizer A chlorine neutralizer refers to a chemical or method to reduce or remove chlorine present in a swimming pool.
  • Chlorine Free Chlorine free is a general term to describe a swimming pool or a chemical added to pool water that does not contain any chlorine or break down in the water to release chlorine.
  • Chloramines Chloramines can form in swimming pool water with levels of chlorine that are too low, and are also referred to as combined chlorine.
  • 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.
  • Cyanuric acid Cyanuric acid is a chemical often mixed with chlorine and is intended to be used in swimming pools to help maintain chlorine levels.
  • Corrosion Corrosion is a general term describing the degradation of pool equipment and surfaces, due to the reaction of unbalanced swimming pool water with these surfaces.
  • Contaminates Contaminates in swimming pools include any foreign substance or material not naturally found in balanced pool water, of which microorganisms and unwanted organic or inorganic compounds are often grouped.
  • Comparator Tube A comparator tube is used to measure and test the level of swimming pool chemicals by adding pool water and adding various chemicals to change the water color to predefined color levels.
  • Combined Chlorine (Chloramine) Combined chlorine (chloramine) is the irritating and smelly creation of free chlorine with organic and inorganic contaminates in the pool.
  • Chlorine Demand Chlorine demand is the estimate of chlorine required to meet the consumption demand of microorganisms that consume chlorine.
  • Chlorine Floater A chlorine floater is a device that floats at the top or slightly submerged, slowly releasing chlorine into the swimming pool water as the water dissolves the chlorine into the water.
  • Chlorine Feeder A chlorine feeder is used for supplying swimming pools with a constant input of chlorine, replacing what is lost in pool water through oxidation of contaminates and neutralized via sunlight.
  • Calcium Hypochlorite Calcium hypochlorite is commonly called shock in swimming pool industry terms, as is used to rapidly sanitize pool water by oxidizing all contaminates in the water.
  • Calcium Hardness (CH) Calcium Hardness describes the measured level of calcium carbonate in swimming pool water.
  • Calcium Chloride Calcium chloride is the chemical compound responsible for the calcium hardness level in swimming pools.
  • Chlorinator Chlorinators are installed as part of the swimming pool plumbing system, responsible for feeding a constant supply of chlorine to the pool water.
  • Calcium Calcium is a mineral important to swimming pools, as calcium is often bound to chemicals added to pool water, plus naturally occurring in the local water source.
  • Chlorine Chlorine is used in swimming pools as a sanitizing agent to disinfect swimming pools, and an oxidizer to help remove contaminates from the pool water.
  • Calcium Carbonate Calcium carbonate is the substance in swimming pools that cause water scaling on pool equipment and pool surfaces.
  • Chelating Agent A chelating agent is a chemical compound designed to combine with other substances, either to bring the targeted substance out of solution or make the substance chemically nonreactive.
