What causes cloudy water?

A number of factors can affect water clarity, including factors you may want to discuss with a pool service professional:

• Are your filters and pumps the right size for your pool? Make sure they provide maximum filtration and acceptable turnover times.
  
• Are your filter elements and filter media in good condition? For DE (diatomaceous earth) filters, elements that are cracked, broken or torn should be replaced. For sand and DE filters, if the filter media is blocked and backwashing does not improve the filtering process, special attention may be needed.
  
• Is the water circulating properly? Make sure suction and return pressures are adjusted to maximize circulation.
  
• Are you vacuuming regularly? Particulates can settle to the bottom of the pool overnight and should be removed before swimming.
  
• Is the water in balance? Use a reliable chemical test kit to ensure the proper levels of pH, total alkalinity and calcium hardness.
  
• Are you oxidizing? Regular, preventive oxidizing with DuPont™ Oxone® eliminates nonmicrobial contaminants, maximizes sanitizer efficiency and makes it easy to keep your pool or spa water clear, sparkling and inviting!
