Tips for Maintaining a Safe and Hygienic Outdoor Spa Bath This Summer

Summer has arrived, and now is the time to get your outdoor spa bath ready for relaxing and cosy evenings under the stars. Spas are a wonderful and welcome addition to many Australian backyards, but they can be difficult to maintain.

Because your spa uses hot water, if it's not maintained correctly, it's more likely than a cold water pool to become a breeding ground for bacteria. This additional growth can make the treatment processes needed to minimise health risks more complex. Here are some tips to ensure that your spa is in perfect condition for the long summer nights ahead.

Get Your Spa Pump Serviced

Like a pool pump, your spa pump requires regular servicing to ensure it's functioning correctly and efficiently. Neglecting your spa pump can negatively impact its energy efficiency, allow a destructive buildup of rust, or allow water to leak into the motor through compromised seals.

At best, a neglected spa pump will be inefficient and noisy enough to ruin the ambience of your evening relaxation time. At worst, you'll need to completely replace the pump, which can be an entirely avoidable expense.

Make Sure You Have the Correct Amount of Sanitiser

Chlorine and bromine are both successful and harmless sanitisers. Sanitiser levels should be in the range of 2.00 to 3.00 parts per million (ppm). However, the amount of sanitiser needed will change based on water temperature as chlorine depletion can occur as the spa temperature increases.  Chlorine depletion can also be caused by a high volume of people using the spa.

Sanitiser levels are important in a small body of water such as a spa because the concentration of contaminants is higher than in a larger pool. You need to add chlorine to your spa because it prevents bacterial growth and reduces your risk of developing infections

Maintain Safe and Effective pH, Hardness, and Alkaline Levels

Having the right pH, hardness, and alkaline levels will reduce chlorine depletion. As a rule, the pH needs to be above 7.2 but not higher than 7.8. A lower pH can increase pool equipment maintenance, eat away grout, and cause eye discomfort for people using the spa. If the pH is higher, spa water can get too cloudy and the filter will require replacing more frequently.

The right alkalinity, or pH buffer, will prevent rapid water chemistry fluctuations. Low alkalinity can make the water corrosive and damage equipment, again adding to unwanted spa costs. High alkaline levels can cause build-up and cloudy water which isn't likely to create an inviting environment for people using your spa.

Water hardness is the level of dissolved minerals in the water.  Low hardness will cause corrosion to the spa equipment and high hardness can cause cloudy water. These negative impacts again can be easily prevented by maintaining hardness levels.

Don't Use Too Much Stabiliser

Commonly called cyanuric acid, stabiliser reduces the amount of chlorine destroyed by sunlight. For a new spa, the recommended level of cyanuric acid is 30 to 50 ppm.  Cyanuric acid is toxic if used in the wrong concentration levels, so it's vital that you get this aspect of pool chemistry right.

Using too much stabiliser can decrease the efficiency of the chlorine, leading to an increase in bacterial growth.  Excessive cyanuric acid can also cause health issues with respiratory and eye irritations.

Getting the most out of your summer can be easy if you follow the above tips.  However, you may still find that getting the balance right is still a little bit confusing.
