The Problem

If your pool is green, black, purple, or brown, let us help transform this to a clear, sparkling blue. Possible causes of discolored water are algae growth or excess copper, manganese or iron. Don't let the color overwhelm you; it may be a simple fix.

Recommended solutions

  • Green, cloudy water (algae growth): See the Algae section for more detailed instructions.
  • Clear, blue-green water (excess copper): Use hth® metal & stain defense according to label directions.
  • Dark green or brown water (excess iron): Use hth® metal & stain defense according to label directions.
  • Black or purple water (excess manganese): Use hth® metal & stain defense according to label directions.

    Preventative maintenance

    • Maintain balanced water.
    • Shock treat the pool weekly.
    • Use an hth® metal & stain defense.

    As always, we’re here to help. If you have questions, contact our help line at 1-866-HTH-POOL or talk to our experts with our live chat!
