How to care for your spa

It is important to keep your spa water clean and bacteria free so you can enjoy and relax in your spa or hot tub. There are several important areas your need to consider when looking after your spa; circulation and filtration, cleaning, testing and water balance, as well as sanitisers, please see below for our guide to your spa or go visit our website and download the Aquasparkle Spa Guide.


Circulation and filtration


The circulation and filtration system within a spa comprises of at least one pump and one filter. The pump circulates the water around the spa and through the filter. The filter’s purpose is to remove the debris, grease and oils from the water. Having both the filter and the pump working correctly and efficiently will mean you have a clean, bacteria free spa.

By keeping your spa filter clean and clear it will allow the filter and chemicals to work efficiently and preserve your spa water. Cascade Pools supplies a range of chemicals and cleaners required to keep your spa clean and healthy, including: Aquasparkle Spa Surface Cleaner and AquaSparkle Spa Cartridge Cleaner.


Aquasparkle Spa Surface Cleaner


To preserve the water quality of the spa, it is essential to remove the debris, for example grass, suntan lotion or leaves. To do so, use Aquasparkle Spa Surface Cleaner. To apply, initially wet the surface, then apply the surface cleaner with a brush, cloth or a sponge, after applying, rinse after a couple of minutes.


Aquasparkle Spa Cartridge Cleaner


Aquasparkle Spa Cartridge Cleaner is an effective way to clean your spa sand filters. Grease and debris can build up within the filter, which can reduce its performance and can also cause a buildup of bacteria. The cartridge cleaner removes all of the debris and oil from the filter as well as the bacteria, which reinstates the filter back to running efficiently. Before use, remove the visible debris and clean the filter with water. After using the AquaSparkle cartridge cleaner, rinse the filter thoroughly before placing it back in your spa.


Testing your spa water


As part of your spa maintenance, it is necessary to test your spa water regularly to check the chlorine or bromine levels, the pH level or the total alkalinity and calcium hardness levels. To check these levels you should use either test strips or pool testers.

Although Test Strips are quick and easy to use, they are not as accurate as the pool testing kits. To use the test strips, simply dip the strip into the water and compare with the colours on the pot. Pool test kits (also known as pool testers) test the chlorine, bromine and pH levels of the spa water by using tablets.

To ensure you have a correct water balance, chemical efficiency is required, protecting the bathers and the equipment and to maintain the water quality. The following points should be considered when caring for your spa (for more information see our swimming pool chemicals section) or download our Pool Care Guide.

  • The pH level of your spa, like swimming pools, should be between 7.2 and 7.6. To correct your pH level use AquaSparkle Spa pH Plus to increase it or Aquasparkle Spa pH Minus to decrease it.
  • Calcium hardness level (how hard the water in your spa is). Use Aquasparkle Spa Hardness Plus if the calcium hardness is less than 10mg/l and Aquasparkle Spa ScaleAway if it is greater than 200mg/l.
  • The total alkalinity measures the spa water’s ability to change the pH. To correct the total alkalinity use Aquasparkle TA if the total alkalinity is below 80mg/l and Aquasparkle Spa pH Minus if above 150mg/l.
  • Total Dissolved Solids (T.D.S.) is the total of all the chemicals, minerals and other debris dissolved in your spa. If your T.D.S. is above 1,500mg/l empty some of the existing water and replace with fresh.


Spa Sanitisers


Spa santisers are required to keep your spa bacteria free. To achieve this you need to use ether a chlorine or a bromine sanitiser regularly.

Chlorine is a popular spa chemical to use. Before using chlorine the spa water needs to be balanced, once this has been achieved the chlorine level needs to be between 3-5 mg/l. There should be no odour if the chlorine is managed correctly. Initially use Stabilised Chlorine Granules to establish the correct chlorine level and then use Spa Multifunctional 20g Chorine Tablets to maintain this level. Bromine is an alternative to chlorine as a sanitiser.

Bromine is more efficient than chlorine over a wide pH range and unlike chlorine is odourless and causes little to no eye irritation. Similar to that if you were using chlorine, initially use Spa Bromine Granules are required to establish the correct bromine level and Aquasparkle Spa Bromine Tablets to maintain this bromine level.
