Why is proper whirlpool water care so important?
The importance of maintaining the water in your hot tub should never be underestimated. If you neglect to care for the whirlpool water, this can not only shorten the life of your wellness oasis, but also pose health risks such as skin irritation, inflammation of the eyes and, in the worst case, even infections.
The reason: the high water temperatures in a whirlpool provide an ideal climate for bacteria, algae and other microorganisms. Without proper care, the water can quickly become cloudy and start to smell unpleasant.
Would you like to buy a hot tub? In order to enjoy your experience to the full and protect your health at the same time, thorough whirlpool water care is essential. In the following sections, we will show you how to care for your hot tub water efficiently.

You should know these basics of hot tub water care
Understanding two factors is crucial for care:
- the pH value and
- the chlorine content in the water.
The pH value determines whether the water is acidic or alkaline and has a major influence on the effectiveness of disinfectants and the comfort of bathing. The optimum pH value of water is on average between 7.0 and 7.6 - in our experience, a value of 7.0 is best. A pH value outside this range can cause skin irritation and reduce the effectiveness of the disinfectant.

The chlorine content is a decisive factor in effectively killing bacteria, viruses, algae and other microorganisms in the whirlpool water. To maintain optimum water quality at all times, it is important to keep the chlorine content in the water within an appropriate range. The optimum chlorine level in the hot tub water depends on various factors - including the water temperature, the number of bathers and the frequency of use. We recommend a chlorine content of 2 ppm and 5 to 8 ppm active oxygen.
Good to know: The chlorine content in the water can decrease more quickly than in a much colder swimming pool due to the high water temperatures in the whirlpool and frequent use. It is therefore necessary to check the chlorine content regularly and adjust it if necessary. This can be done by adding (multifunctional) chlorine tablets, chlorine granules or other suitable disinfectants.
Chlorine-free water care in whirlpools is also possible. This has gained popularity in recent years as many people are looking for alternative methods of disinfection that cause less skin irritation and a more pleasant odor. Choosing the best method for chlorine-free water care depends on your personal preferences, local regulations and the specific requirements of your hot tub. Our team on this.
Step by step to efficient water care for your whirlpool
Efficient water maintenance of a whirlpool includes weekly, monthly and semi-annual tasks.
Weekly tasks:
- In the first two months, you should check the pH value every 1-2 weeks - then every 3-4 weeks. Test kits and test strips are helpful for measuring the values and making adjustments if necessary.
- Once a week you should use chlorine tabs, a whole measuring cup of active oxygen and 2-3 caps of water clarifier.
Monthly tasks:
- When filling the whirlpool for the first time, you should use 4-5 caps of anti-scale, then 1-2 caps once a month.
- You should carry out a thorough inspection and cleaning of the whirlpool once a month. This includes checking the jets, pump and other components for wear or blockages.
Semi-annual tasks:
- You should change the filter after 6 months at the latest - otherwise the warranty may become void. Good filter maintenance is crucial, as the filter is responsible for removing dirt, particles and impurities from the water.
- At the same time, we recommend that you drain the spa completely, clean it and refill it with fresh water to prevent the build-up of minerals and other deposits. It is best to use pipe cleaner before draining.
The right water care products for your hot tub
Choosing the right water care products is also very important. We recommend our pool chemistry starter kitwhich contains all the necessary products such as pH raisers, pH reducers and chlorine tablets for your hot tub. For correct use, we have a whirlpool water care instructions for you.
Please always follow the safety instructions and dosage recommendations on the products to avoid over- or underdosing. This is the only way to optimally maintain the water quality in your whirlpool - and at the same time extend the service life of your whirlpool.
How to solve occasional water problems
Occasionally, there may be problems with whirlpool water care. We explain what you need to do if this happens.
Occasional water problems include:
- cloudy water
- green water
- Unpleasant odors
Cloudy water may indicate poor filtration or inadequate water chemistry. Make sure your pH is in the correct range by checking, cleaning or replacing your filter.
Green water is often due to the growth of algae in the hot tub. To get crystal clear water again, you should carry out a shock chlorination. After this, you should not go into the water for 24 hours. You should then check whether the chlorine content in your hot tub is within the recommended range.
Unpleasant odors may indicate a high level of organic impurities such as skin oils, cosmetic residues or urine. Shock chlorination and the addition of enzymes to the water treatment can help to break down these impurities. After this, you should not go into the water for 24 hours. You should then check whether the chlorine content in your hot tub is within the recommended range.
Conclusion
Thorough hot tub water care is important to protect your health, maintain water quality and extend the life of your hot tub. From regularly checking the pH and chlorine levels to the correct choice and dosage of hot tub water care products, regular maintenance of your hot tub water is essential.
