Is your swimming pool water not looking quite right? 

Has it turned an abnormal colour, or is it cloudy? 

Before you panic and start thinking about draining your pool, here is what your water is trying to tell you and how to fix it…

What to do if your pool water is green

If your pool water is looking green, the culprit is algae. The darker the shade of green, the worse the problem is. Algae can develop when your pool’s sanitizer levels are too low. 

To remove the algae from your water you will need to:

  • Carefully vacuum your pool and then use an algae brush to give it a good scrub 
  • Test your water
  • Shock your pool
  • Turn on your pool’s filter and let it run for a few days until the water looks normal
  • Re-test your water and ensure that it is now properly balanced
  • Keep a close eye on your sanitizer levels to ensure the algae does not return

 

What to do if your pool water is cloudy

Cloudy pool water is a sign that either your filter is no longer functioning properly, or that your pool’s chemicals have become unbalanced. 

To return your water to normal you will need to:

  • Test your water to see if the issue is with your chemicals
  • If your chemicals are out of balance, shock your pool
  • Re-test your water and ensure that it is now properly balanced
  • Even if your chemicals are out of balance you should also check your filter and give it a good clean.
  • Make sure your filter it is the right size for your pool
  • Run your filter more often, especially if you are using your pool more, to avoid the cloudy water returning

What to do if your pool water is reddish-brown

If your pool water is reddish-brown, this is an indication that your pool’s iron levels are too high. This is definitely a cause for concern because this colour can permanently stain your pool if it is not dealt with immediately. 

To remove the iron from your water you will need to:

  • Get a test kit that measures your pool’s iron levels, which you can find at your local pool supply store
  • Purchase special iron removing chemicals 
  • Shock your pool using those special chemicals
  • Re-test your water and ensure that it is now properly balanced

What to do if your pool water is making your eyes very irritated when you swim

If your eyes feel more irritated than usual and look red after swimming, this is a sign that your pool’s chlorine levels are unbalanced. If this is left untreated, it can cause further irritation to your skin or even lungs. 

To rebalance your pool’s chlorine levels:

  • Test your water
  • Shock your pool
  • Re-test your water and ensure that it is now properly balanced

There are more factors that can affect your water, such as animal visitors or rain, so it is important to stay on top of your pool testing schedule in order to ensure that your pool’s chemicals stay balanced.
