San Diego Algae Treatment

Pool Algae in San Diego

Algae is a common pool problem, especially in warmer climates like San Diego. It can quickly take over your pool if not addressed early. Here are the key signs you may have algae:

  • Discolored water (green, yellow, or cloudy)

  • Slimy or slick pool surfaces

  • Visible patches or streaks on walls, steps, or floors

  • Rapid chlorine loss despite regular dosing

  • Poor water circulation or filtration performance

Algae can be more than just an eyesore—it can damage pool surfaces, clog filters, and throw off your water chemistry.

Common Types of Pool Algae

  • Green Algae

    • The most common type

    • Turns water green and can spread quickly

    • Usually floats in the water or clings to walls

    • Often a result of poor circulation or low sanitizer levels

  • Yellow (Mustard) Algae

    • Appears as yellow or brown dust-like patches

    • Typically clings to shady areas or pool walls

    • More resistant to chlorine and can return easily if not treated thoroughly

  • Black Algae

    • Dark spots or patches with a protective outer layer

    • Grows deep into porous surfaces like plaster or grout

    • Very tough to eliminate and often requires brushing and chemical treatment

  • Pink Algae (technically not algae, but bacteria)

    • Slimy pink or red streaks often found around plumbing or in corners

    • Less common, but can be persistent without proper sanitation
