Problems with Chlorine in Hot Tubs

Chlorine is considered to be the cheapest form of santizer for your hot tub water but did you know that it is probably the worst choice you can make. It's the most difficult and time-consuming sanitizer to use and is not well suited to hot tubs.

Just take a look at these FOUR reasons why you should look for an alternative to Chlorine...

1. It's complicated and time consuming!

Adding Chlorine to spa water is not straightforward. You need to get the Total Alkalinity, pH and Calcium Hardness levels (otherwise known as 'balancing') in your water just right and always before you add any Chlorine product, otherwise the chlorine becomes ineffective and won't sanitize! Just the process of adding Chlorine granules or tablets to the water has a tendency to alter the pH value still further so you need to constantly keep testing and adjusting the water's balance. It can be a never ending loop!

Chlorine added to 'unbalanced' water will create Chloramines that do nothing to clean your hot tub's water and will just leave a 'bleach' like smell above the water's surface.  

2. It's not always good for your body!

Exposure to chlorine compounds and their byproducts often result in allergic reactions and skin irritation. When such substances combine with organic matter like urine, sweat, etc. it leads to the development of dichloramines, monochloramines, and trichloramine, which are strong irritants. Some of the symptoms that can be caused by Chlorine exposure include:

  • dry and itchy skin. The resultant case of chlorine rash may elicit peeling of the skin.
  • coughing and sneezing.
  • nausea, vomiting and pain in the abdomen.
  • short term problems in breathing and pain in the chest.

3. It can ruin your bathing costumes!

Bathing costumes used in hot tub water at its normal operating temperature, combined with a Chlorine sanitizer will suffer from high levels of colour fade as well as losing their elasticity.

Chlorinated water produces hydrochloric and hypochlorous acids. The latter is a component found in household bleach which, if spilt on your clothes will cause permanent damage.

4. It's not good for your eyes!

In a hot tub, the pH value of the water is the major factor in eye irritation. A well maintained tub will keep the pH balance as close to 7.4 - 7.6 as it can ie as close to matching your body's natural pH balance as possible.

The addition of Chlorine will lower the pH of the water and and cause it to irritate your eyes.

In any hot tub, the chlorine does not always oxidize the organic matter in the water completely. This residue consists of a whole range of organic compounds, including Ammonia, which can cause further eye and skin irritation.
