Spa treatment test for cloudy water

by Steve

Cloudy spa water troubleshooting. We are sometimes asked- “Which is the best spa treatment when my water is cloudy?”.  Well it’s certainly time to take some action, but first you must test your spa water for Total Alkalinity and pH.

Why do I have cloudy spa water?
Cloudy spa water can be caused by high alkalinity and can be corrected by adjusting pH. High Total Alkalinity makes pH adjustments more difficult and can be a contributing factor in cloudy water and scaling. A knock on effect is that high pH can then lead to a loss of chlorine or bromine effectiveness and increased risks of scaling and cloudy water.

Balancing your the spa chemical levels is the key to keeping your hot tub safe to use.  Here follow some tips about maintaining your hot tub spa water chemistry.  You can also read our review of the best selling spa water treatments.

Testing Spa Water
By using simple test strips you can get a good idea of your hot tub’s spa chemical levels. You simply dip the strip in the water and match the changing colours against those on the container.

A basic test strip test will show readings for Total Alkalinity, pH and Free Chlorine.

Total Alkalinity
The basic Alkaline substances in your hot tub spa water will act as a buffer against sudden changes in the pH. Total Alkalinity should be at between 80 and 150 ppm and corrected before adjusting the pH or Chlorine levels.

pH
pH refers to the acid condition of your water on a scale from 0 to 14. 0 is very acid and 14 is very alkaline. High pH leads to a loss of chlorine effectiveness where as a low pH leads to corrosion from a higher acid content. The pH levels in a spa must be within a range of 7.2 – 7.6 .

Free Chlorine
Free chlorine in water is a good thing when you’re using a chlorinated treatment system.
You’ll need to maintain a balance of free chlorine in your tub because that’s what that mops up (oxidizes) any contaminants. For hot tubs and spas the recommended level of free chlorine is 3 to 5 ppm.

Spa treatment when water has high alkalinity
High pH and high alkalinity will cause a build up of calcium in your tub. This will show in the form of white scaling deposits or staining. A way of reducing high alkalinity is to add a treatment containing dry acid or Sodium Bisulfate. A product such as Spa Down can first reduce Total Alkalinity and then PHB to balance pH.

Spa treatment for low alkalinity in water
To raise alkalinity in spa water you can add a treatment containing Sodium Bicarbonate. Try Spa Up to raise the alkalinity and the PHB to balance pH.

Spa treatment when my water is yellow
High pH above 7.8 could be causing cloudy yellow spa water. Alternatively, if you’re using chlorine and have a high pH there may be a reaction between it and any metal content thus causing the yellow color. Maybe try changing over to a bromine or non-chlorine based system.
Yellow spa water could also indicate an algae problem. To kill off any algae try draining and re-filling your tub and then applying a strong chlorine shock to kill off any micro-organisms. Let the shock do its work for about 8 hours and then re-test. Changing your filter before re-filling would also be a very good idea.

Important Info
After adding spa chemicals to your hot tub always allow time for your water to circulate and mix properly for a few hours before re-testing.
For the best testing results when checking spa chemical levels, take a sample of the spa water into a small container and test it after it has cooled.

The final step is to rinse and apply lotion. “Your skin is going to feel really smooth,” Carney tells her clients. Most clients tell her the treatment is also relaxing.
