The number of private pools and swimming pools has been increasing relentlessly in Germany for years. Due to Corona regulations, fewer people were on vacation in 2020 and 2021 and invested money in their swimming pool. Pool builders have years of waiting lists. But once construction is complete, how do you ensure proper water quality?
What can go wrong?
Much! On the other hand, the water used in the entrance cannot be of sufficient quality for the swimming pool because it is contaminated with toxins or microorganisms. Harmful bacteria or fungi can also settle in swimming pools — or toxic byproducts can build up if improper disinfection. This can be summarized under the term health risks. If bathing is not safe for people, urgent remedial action should be taken.
Another possibility is a visual problem: cloudy or discolored water, algal growth, poorly soluble mineral deposits or bacterial mats. These are not necessarily toxic, but they make the pool look disgusting and thus reduce the fun of bathing. Erosion risks to swimming pool infrastructure can also be categorized here.

To be on the safe side, it’s a good idea to hire a lab to do a thorough water test. On the other hand, it can help to check the quality of the water that the pond is filled with. On the other hand, it is also possible to monitor important factors during the operation of the swimming pool. The hardness of the water, the pH value and the presence of harmful bacteria are decisive factors in this. There are a number of potential pathogens that can breed in shower water. If they are not stopped in time, they can sometimes cause serious illnesses.
In more extensive investigations, other types of stress may also be tested. Use for example as a water source, it makes sense to check it for contamination with heavy metals and other pollutants.
What to look for when using the pool
Even before the first water is allowed in, several building regulations must be observed. These ensure that swimming pools are built only in places where they do not pose a danger to people or the environment and create the prerequisites for safe operation.
In order to ensure the cleanliness of the water, many factors must be taken into account. Regular pool cleaning with chlorine-containing chemicals is no longer the best because it can create irritating substances that increase sensitivity and can lead to skin reactions in sensitive people. Saltwater aquariums, which are advertised as gentler, ultimately work with chlorine: here the active substance is created by electrolysis of chloride dissolved in water. Active oxygen (H2O2) and UV rays are more compatible with the skin and the environment. Ozone therapy for private users is excluded in any case.
For these methods to work safely, certain conditions must always be met. The most important condition is the optimum pH adjustment. Most disinfection variants work efficiently only when the pH of the water is in the range of 7 to 7.4. If it deviates from this, it must be corrected by adding buffer solutions.
The water condition is constantly changing, mainly due to bathing activities, but also due to temperature fluctuations and precipitation. Therefore it is important to check the quality regularly or have it checked by professionals. Although there are some ground rules (eg, frequent cleansing when showering is heavy), it is always best to measure and act accordingly.
