Having your own hot tub is a great way to relax and relieve stress. However, to ensure that the experience remains pleasant, the right water quality is crucial. The pH value plays a key role here, as it influences the chemical composition of the water.
An optimum pH value in the whirlpool tub not only ensures a pleasant bathing experience, but also protects the components of the whirlpool tub from damage.
What is the pH value and why is it important?
The pH value indicates how acidic or alkaline a liquid is. The scale ranges from 0 to 14, with 7 being neutral. Pure water, for example, has a pH value of around 7. A pH value below 7 is acidic, while a value above 7 is described as basic or alkaline.
The pH value in the whirlpool should be between 7.0 and 7.4. This ensures efficient disinfection of the water and protects bathers' skin and eyes from irritation. The pH value also influences the effect of disinfectants such as chlorine.
If the pH value is too high, chlorine cannot work effectively, which is why germs and bacteria multiply more easily. A pH value that is too low, on the other hand, leads to aggressive chlorine, which irritates bathers' skin and causes an unpleasant odor.
Optimum pH value in the whirlpool tub
The ideal pH values for whirlpools are between 7.0 and 7.4. A pH value in this range ensures effective disinfection and a pleasant bathing experience.
Deviations can cause various problems such as skin and eye irritation, foaming, poor disinfection efficiency, cloudy water and corrosion of metal parts in the hot tub. It is therefore important to measure the pH value regularly and adjust it if necessary.
Measuring the pH value in the whirlpool tub
Special test strips or digital pH meters are available to measure the pH value in the hot tub. Regularly checking the pH value, ideally at least once a week, is essential. To do this, immerse the test strip or meter in the water and read the value from the color change or the digital display.
Causes of fluctuations in the pH value
Many factors can influence the pH value in the hot tub. Internal factors include user behavior and the use of bath additives.
External factors such as environmental pollution, rain and water replenishment can also change the pH value. An incorrectly set value can not only have an unpleasant effect on bathers, but can also impair the effectiveness of other pool care products.
Dealing with an incorrect pH value
If the pH value is too low, this can lead to eye and skin irritation and impair the disinfecting effect of chemicals.
A pH booster, such as pH-Plus, helps to raise the value and bring the water back into the optimum range. However, if the pH value is too high, the water can become cloudy and smell unpleasant.
A pH reducer, such as pH-Minus, helps to lower the pH value and make the water clear and odorless again.
Wrong pH values at a glance:
- Low pH value: eye irritation, weak disinfection
- High pH value: cloudy water in the whirlpool tub, bad odor
- Use pH raiser (pH plus) and pH reducer (pH minus)
Tips for long-term pH balance
For a long-term balance of the pH value in the whirlpool, regular checks and maintenance work should be carried out. Recommended measurement frequencies are weekly, or more frequently with heavy use.
The water should also be changed and cleaned regularly to ensure good water quality. Record the measured values and your measures to identify patterns and make water care more effective.
Note: Regular checks and logging help to ensure water quality in the long term.
