algaecides

Pool algaecides are used to prevent and control algae growth. While sanitizers and oxidizers help keep water clean, algaecides specifically target algae before it spreads and becomes a bigger problem. 

When to use an Algaecide

  

  • To prevent algae growth before it starts
    Algaecides stop algae spores from multiplying, especially during warm weather.
     
  • When water begins to turn green, yellow, or cloudy
    Early signs of algae are easier to treat with algaecide before a full bloom occurs.
     
  • If pool surfaces feel slippery
    Slippery walls, steps, or floors are often an early indicator of algae.
     
  • After heavy rain or storms
    Rain introduces spores, debris, and nutrients that algae thrive on.
     
  • During periods of high heat and sun exposure
    Warm water and sunlight create ideal conditions for algae growth.
     
  • As a preventative treatment during peak swim season
    Routine algaecide use helps maintain clear water and reduces the risk of outbreaks.
     
  • After killing algae with chlorine or shock
    Algaecides help prevent algae from quickly returning.
     
  • When opening or closing the pool
    Algaecides are commonly used during seasonal transitions to protect water quality.

Problems Algaecides Correct

  • Green, yellow, or black algae
     
  • Slippery pool walls and steps
     
  • Cloudy water caused by algae growth
     
  • Recurring algae blooms
     
  • Stains caused by untreated algae
