• Etching Etching is a problem encountered by pool owners with low calcium hardness or pH, where the pool water becomes corrosive to concrete, stone, or metal surfaces exposed to the pool water.
  • Electronic Chlorine Tester Electronic chlorine testers are available that can test chlorine levels in swimming pools easier and just as accurately as other test methods.
  • Electric Pool Heater Electric pool heaters are used to heat swimming pool water, and use electricity as their main source of heating.
  • Evaporation Evaporation is the process of water in liquid form turning into water vapor. This process occurs naturally in swimming pools, decreasing the overall volume of water present in the swimming pool.
  • Electronic pH Tester Electronic pH testers are handheld devices that are used to measure the pH level of swimming pools, intended to reduce the manual work involved via testing pH using other methods.
