How to keep the water in your spa nice and clean

As a rule of thumb, there are two things you need to keep an eye on regarding water chemistry: Amount of chlorine and pH-levels.

Chlorine in the water helps fight bacteria and alogea. That is why it is crucial to regularly check the amount of chlorine in the water of the spa.

The pH-level determines the waters ability to avoid limescale deposits and algea growth. If the water is too alkaline (pH above 7,5) you risk getting clear limescale deposits in your spa. On top of that, the effect of the chlorine will be reduced if the pH-level is too high.

Anyway, enough about the scientific stuff - let us fix that water!

We have drawn up a schedule for you, so you know what to do when to get optimal hygiene in your spa water. We also have a more thorough check list in our article "How to get (and keep) a healthy water chemistry".


  • Remove visible dirt and grime from the tub
  • Make sure the cover is put on correctly and properly secured. This keeps out dirt and retains the heat more effectively
  • Look for visible changes to the spa and the water - including those appearing gradually over several days

Weekly (the most important tests!)

You should check the amount of chlorine and pH-level of the water every week. You do this with our test strips, that measures both chlorine and pH.

Keep the strip in the water for about five seconds, take it out of the water and allow it to dry for about 15 seconds. Afterwards, you compare the colors of the strip to the guide on the packaging for the strips.

  • Ph-level should be between 6.8 and 7.2
  • The amount of chlorine should be between 1 and 2 mg per litre of water

If the pH-level is to high, use pH-Minus to get the water down to the optimal level. Is the pH-level too low, fix it by adding fresh water to the spa.

If the water is low on chlorine, use either Chlorine Granules or Chlorine Tabs to get the water to the appropriate level.

The filters remove little particles and impurities in the water, making it very important to clean these. Take the filtres out of the spa and put them in a bucket with af mixture of water and Filter Clean. After thorough cleaning, you simply put the filtres back into the spa.

Always follow the instructions on the produvts to avoid harm to the spa or people!

Feel free to finish off by checking the water for larger particles at the bottom of the spa and in the water in general. You might want to use a  Spa Vacuum to get rid of any impurities on the bottom of the tub.


  • Make sure that the system is working flawlessly. Check for leaks from the pipes, listen for unusual sounds from the pumps and so on. Please see the instructions for your spa for a guide on how to perform a system check
  • Clean all around inside the tub at the waterline. Use a soft cloth or sponge
  • Make sure the water level is correct (should be about the middle of the shimmer opening)

Every third month

Change the water of the spa completely. Even though you follow this guide, it is always a good idea to regularly change the water to get rid of old chemicals and the likes.

You might want to use Spa Cleanser during this process, as you have to empty the spa of water when using the cleanser anyway.

It may seem unmanageable - but it is not!

We gladly admit, there are a lot of things to keep in mind in this guide. But we would rather make a comprehensive guide with too much information than too little to make sure, you can make your spa work for as many years as possible.
