Everything you need to keep your water crystal clear

Take good care of the water in your spa to keep it hygienic for your next dip.

In order to fully enjoy your spa, you need to keep the water clean. Here, you will find everything you need to keep the values ​​of the water straight.

The hot water in a spa is typically near 40°C, and this increases the risk of algae and bacteria growth. Therefore, it is important to keep track of both the chlorine content of the water and the pH value. That way, you are sure that the water is clean.

We have everything you need to ensure the chemistry of your spa. In addition, we have created a guide to how often you should check different things regarding the water in your spa. You can find it at the bottom of the page.

How to keep the water clear and clean

There are basically two things you need to keep an eye on in terms of the chemistry of your spa water: Chlorine content and pH.

Chlorine in the water helps fight bacteria and algae. Therefore, it is important for hygiene that the chlorine content of the water is always in place.

The pH value is crucial for both limescale deposits in the spa and algae growth. If the water is too alkaline (pH above 7.5) you risk clear limescale deposits in your spa. At the same time, the effect of chlorine in the water is greatly reduced if the pH value is too high.

Well, enough about that scientific ... let's get a handle on that water!

We have made a plan for you so you know what to do when to get the most hygienic water in your spa.

Every day

  • Remove visible dirt and grime from the water
  • Make sure the spa cover is properly attached and fully secured. It keeps dirt out and keeps the heat better at the same time
  • Look for visible changes on the spa and in the water - even those that appear over several days

Every week (the important tests!)

You should check the chlorine content and pH of the water every week. You do this with our test sticks, which measure both chlorine and pH value.

Keep the whole stick in the water for approx. 5 seconds, pick it up and let it dry for approx. 15 seconds. Then compare the colors on the strip with the guide on the test stick package.

  • The pH value should optimally be between 6.8 and 7.2.
  • The chlorine content should preferably be between 1 and 2 mg / liter.

If the pH of the water is too high, you can use PH-Minus to get the water down to the right values. Conversely, if the pH is too low, you can fix it by pouring fresh water into the spa.

If there is a lack of chlorine in the water, use chlorine granules or chlorine tabs to get the right value.

The filters take care of removing small particles and impurities in the water, and therefore it is important to clean these as well. Take them out of the spa and clean them in a bucket of water and Filter Clean. After thorough cleaning, put them back in.

Always follow the instructions on the products carefully to avoid damage to the spa or people!

Finish off by examining the water for larger particles at the bottom of the spa or in the water in general. You can conveniently use a bottom suction tool to remove any impurities on the bottom.

Every month

  • Test that the system runs flawlessly. See if it is leaking from the pipes, listen for noise from the pumps, etc. Please see the manual for your spa to see how to do a system test
  • Clean all the way around the waterline. Use a soft cloth or sponge
  • Make sure the water level is correct (must be in the middle of the skimmer opening)

Every third month

Change the water in the spa. Even if you follow the guide here, it is always a good idea to provide fresh water from time to time.

You can possibly use the spa cleansers at the same time, as you still have to empty the spa of water after using this.

It may seem confusing - but it is not!

We are happy to admit, there are many things in the guide here. But we would rather make a detailed guide with a little too much than a little too little, so you are sure to extend the life of your spa.

You are always welcome to contact us if you have questions about the guide or the products!
