Problem of the Month: Water Discoloration


What is it?

There are various reasons for water discoloration, and it may be best to speak to your pool professional to determine what the cause is – Algae or Metals.

Your pool professional should have a serious of questions they will ask to help determine the cause to help you find the proper solution:

  • Are you on well water or city?
  • What is your Chlorine level?
  • How has your chlorine been in the last few weeks?
  • How long has the pool been up and running?
  • Do you turn your pool off at night?
  • How does your water feel?
  • Does your water change color when adding chlorine shock?


If the determination is that the pool has algae, then your preventative measure will be following your weekly pool regime – Sanitize, Shock, and add Algaecide along with Brushing the pool walls.

If the issue is caused by metals in the water, then using a garden hose adapter when topping up water will eliminate metals before they even get into your pool.  You could use a product such as BioGuard’s Pool Magnet Plus as part of your weekly regime to prevent a future color change in your pool water.
