What are the most important pool water values?
To ensure pool water remains hygienic and crystal clear, it's important to regularly check the water quality. There are several key pool water parameters that must be measured and monitored. This article introduces the most important water parameters:
- pH value: The pH value is a measure of the acidity of the water and influences the effectiveness of disinfectants. The optimal pH value for pool water is between 7.0 and 7.4, as this corresponds to the pH value of the human eye and mucous membranes.
- Chlorine level: Chlorine is the most important disinfectant for pools, killing bacteria, viruses, and other germs. The chlorine level should be between 0.5 and 1.5 ppm.
- Cyanuric acid level: Cyanuric acid is a chlorine stabilizer that prevents sunlight from breaking down chlorine. The recommended cyanic acid level is between 30 and 50 ppm.
- Redox value: The redox value measures the oxidation and reduction processes in the water and is an indicator of the effectiveness of disinfectants. The optimal redox value for pool water is between 650 and 750 mV.
- Alkalinity: Alkalinity is a measure of the carbonates and bicarbonates in water and influences the pH value. The recommended alkalinity level is between 80 and 120 ppm.
By regularly measuring and monitoring these important water parameters, you can ensure that your pool remains hygienic and clean, allowing you to enjoy swimming and relaxing in your own pool.

Problems caused by poor water quality
Poor pool water quality can lead to a variety of problems that can spoil the swimming experience and even pose health risks. Therefore, regular pool cleaning is essential.
Green water is a common problem with poor water quality, especially low chlorine levels. This green water is caused by the growth of algae, which thrives in an oxygen-rich environment. Aside from the fact that green water looks uninviting, algae can also cause slippery pool surfaces, increasing the risk of falls.
Another problem with poor water quality is unhygienic water. Inadequate disinfection of the water can lead to the proliferation of bacteria and viruses, which can pose a health risk to bathers. A pH value that is too low can reduce the effectiveness of the disinfectant, leading to increased proliferation of bacteria and viruses.
Limescale deposits can also be a problem with poor water quality. If the pH level is too high, increased limescale buildup can occur on the pool walls, floor, and fixtures. These deposits can be difficult to remove and can seriously impair the pool's appearance.
Finally, a pH that's too low can also lead to corrosion of pool components such as pumps, filters, and heaters. This can result in significant repair costs and shorten the lifespan of these components.
It's therefore important to regularly monitor pool water quality and take action as needed to prevent problems. Proper water disinfection and treatment is key to a clean, safe, and enjoyable swimming experience in your own pool.

How are pool water values measured?
Measuring pool water parameters is an important step in water care and treatment. There are several ways to measure water parameters.
The simplest method is manual measurement using test strips. This involves immersing the test strip in the water for a few seconds and then comparing the color change with a color scale. However, this method is not very accurate and can lead to inconsistent results.
A more accurate method is to use an electronic pool tester. A water sample is placed into the device, which then automatically measures and displays the various water parameters.
An example of such an electronic pool tester is the Poollab 2.0 . This tester measures pH, free and combined chlorine, alkalinity, cyanuric acid, and calcium hardness and displays the results digitally. This method is highly accurate and allows for the measurement of multiple values simultaneously.
Another advantage of electronic pool testers is their memory function, which allows you to log and monitor readings over time. This allows you to quickly and easily determine whether water parameters have changed over time and take appropriate action.
Ultimately, the choice of measurement method depends on individual needs and requirements. Those who value accurate measurements and quick evaluation of the results should opt for electronic pool testers.

Which values are important in a chlorine pool and which are important in a saltwater pool?
For a pool with normal, chlorinated water, the most important water values are the pH value and the chlorine content.
The pH value should be in the range of 7.0 to 7.4 to ensure optimal effectiveness of the chlorine and to avoid skin and eye irritation.
The chlorine content should be between 1 and 3 ppm (parts per million) to ensure adequate disinfection and prevent the growth of algae and bacteria.
For a saltwater pool, the most important water values are also the pH value and the salt content.
The pH value should be in the range of 7.0 to 7.4 to ensure optimal effectiveness of the salt electrolysis system and to avoid skin and eye irritation.
The salt content should be between 3,000 and 4,000 ppm to ensure sufficient conductivity for the salt electrolysis system.
Unlike a chlorinated pool, a saltwater pool system is powered by salt electrolysis, which produces chlorine from the salt in the water. This eliminates the need for the pool owner to manually add chlorine, providing a convenient and environmentally friendly alternative.
However, it is important to note that the salt in the water must be checked regularly to ensure that the salt content remains within the optimal range and that the salt electrolysis system is functioning properly.
In addition, the salt content in pool water can change due to evaporation or water addition, so regular checks and adjustments are necessary to maintain water quality.

Pool water values explained
PH value
The pH value is an important parameter for pool water quality. It provides information about the acidity of the water.
The pH scale ranges from 0 to 14, with pH 7 being neutral.
If the pH value is above 7, the water is alkaline; if it is below 7, the water is acidic.
The optimal pH value for pool water is 7.4, as this corresponds to the pH value of the human eye and mucous membranes. A pH value of 7.4 also provides good chlorine disinfection.
A pH that's too low can lead to aggressive water that damages the pool's mechanical components. It can also cause eye and mucous membrane irritation and damage the pool liner.
Too high a pH value can lead to poor chlorine disinfection, cause skin irritation, limescale precipitation and turbidity.
Sodium bisulfate can be used to lower the pH. Sodium carbonate can be used to raise the pH.
It's important to check the pH of your pool water regularly and adjust it as needed. This can be done using pH test strips or a pH tester.
Another important measure for maintaining pH is the use of buffer solutions. These solutions help keep the pH stable and minimize fluctuations.
By regularly checking and maintaining the pH level, you can ensure that the pool water remains in optimal condition and avoid health problems.
Chlorine value
The chlorine level in pool water is an important parameter for water quality. Chlorine is a disinfectant that kills bacteria, viruses, and other contaminants in the water. The optimal chlorine level for pool water is between 0.5 and 1.5 ppm (mg/l). If the chlorine level is too low, bacteria can multiply and the water becomes cloudy. If the chlorine level is too high, it can cause skin irritation, burning eyes, and an unpleasant odor.
There are two types of chlorine compounds: organic chlorine and inorganic chlorine. Organic chlorine, such as trichloroisocyanuric acid and dichloroisocyanuric acid, is suitable for weekly chlorination and dissolves quickly. Inorganic chlorine, such as calcium hypochlorite and sodium hypochlorite, is suitable for daily and shock chlorination and works faster than organic chlorine.
Free chlorine is the chlorine available in water that kills contaminants. Combined chlorine (also called chloramines) is formed when free chlorine reacts with organic substances such as sweat, urine, and skin particles. Combined chlorine is ineffective and can cause eye and mucous membrane irritation. To reduce the combined chlorine, the pool must be shocked with calcium hypochlorite to convert the combined chlorine into free chlorine.
To measure the chlorine level in pool water, a test kit or electronic pool tester is used. Most kits measure free chlorine, but to measure combined chlorine, you need to measure total chlorine. Total chlorine is the sum of free and combined chlorine.
An electronic pool tester such as Poollab 2.0 measures both the free chlorine content and the total chlorine content.
To maintain the chlorine level in the pool water, it must be chlorinated regularly. Chlorine consumption depends on various factors, such as swimming frequency, water temperature, and sunlight exposure.
Too low a chlorine level can lead to insufficient disinfection of the pool water, thus endangering the health of bathers. Bacteria, viruses, and other germs can multiply unhindered and cause infections. Too high a chlorine level, on the other hand, can lead to skin and eye irritation, and respiratory problems.
If the chlorine level is too low, you can take the following measures:
- Increase the amount of chlorine added. Regularly checking the chlorine level is important to ensure it remains within the optimal range.
- Check the pH level. A pH level outside the optimal range can impair the effectiveness of the chlorine. A pH level of 7.4 is ideal.
- Check the condition of the filter. A dirty filter can impair the effectiveness of the chlorine treatment.
If the chlorine level is too high, you can take the following measures:
- Dilute the water. Add fresh water to reduce the chlorine level.
- Use a chlorine reducer. These products are commercially available and can reduce chlorine levels.
- Check the pH level. A pH level outside the optimal range can impair the effectiveness of the chlorine. A pH level of 7.4 is ideal.
- Leave the pool unused for a while. Chlorine levels will decrease over time if the pool is not used.
In any case, it is important to check the chlorine level regularly and ensure that it remains within the optimal range.
Redox value
The redox value is a measure of the oxidation and reduction potential of the pool water.
It indicates the number of positive and negative ions present in the water and whether the water is oxidizing or reducing. The optimal redox value for pool water is between 650 and 750 mV.
The redox value indicates the extent to which the water is able to break down organic contaminants.
A redox value that is too low (below 600 mV) means the water is reducing and therefore cannot adequately kill germs and bacteria. This can lead to health problems such as skin and eye irritation. To increase the redox value, you can treat the pool water with an oxidizing agent such as hydrogen peroxide or active oxygen.
A redox value that is too high (over 800 mV) means the water is oxidizing and can therefore attack even healthy cells in the body. This can lead to eye and mucous membrane irritation, as well as skin rashes. To lower the redox value, you can treat the pool water with a reducing agent such as sodium thiosulfate.
To measure the ORP (redox) value of your pool water, you'll need a ORP meter or test kit. Regularly checking the ORP and taking appropriate measures to keep it within the optimal range will help ensure your pool water remains hygienic and healthy.
Cyanic acid value
The cyanuric acid level, also known as the stabilizer level, is a measure of the cyanuric acid content in pool water. Cyanuric acid is an important component in pool maintenance because it stabilizes chlorine and protects it from degradation by UV rays. The recommended cyanuric acid level is between 30 and 50 ppm (mg/l).
A cyanuric acid level that's too low causes chlorine to break down faster, resulting in higher chlorine consumption and higher costs. However, a cyanuric acid level that's too high can lead to chlorine blockage, rendering the chlorine ineffective and unable to combat bacteria and algae.
Too high a cyanuric acid level can also lead to health problems, as it increases the pH of the water and can cause eye and skin irritation. Too low a cyanuric acid level can also cause health problems, as it can lead to an overdose of chlorine, which can cause respiratory problems and skin irritation.
If the cyanuric acid level is too low, cyanuric acid should be added to the pool water. If the level is too high, the water should be diluted to lower the level. One way to lower the cyanuric acid level is to dilute the water by partially draining it from the pool and replacing it with fresh water. Another option is to use special products to lower cyanuric acid levels.
It is important to regularly check cyanuric acid levels and, if necessary, take action to keep them within the optimal range. This not only increases the effectiveness of pool maintenance but also ensures the health and safety of pool users.
TA value (alkalinity)
The TA value stands for the total alkalinity value of the pool water. It measures the total alkalinity content in the pool water and is an important indicator of water quality.
Alkalinity indicates how much buffering capacity the water has to compensate for changes in pH.
The optimal TA value for pool water is between 80 and 120 ppm (mg/l).
Too low alkalinity can cause the pH to become unstable and change rapidly. Too high alkalinity can cause the pH to remain too high.
Too low alkalinity can have the following health consequences:
- Irritation of the eyes and skin
- Corrosion of metal parts in the pool
- Damage to the pool liner
- rapid pH fluctuations
To increase alkalinity, you can use sodium bicarbonate or an alkalinity regulator. To decrease alkalinity, you can use diluted hydrochloric acid or a pH reducer.
Excessive alkalinity can have the following health consequences:
- Cloudiness of the pool water
- Damage to the pool liner
- Problems adjusting the pH value
Spring: Reopening the pool
Spring is here, and with it comes the anticipation of swimming in your own pool. But before that happens, the pool needs to be awakened from its winter slumber and put back into use. A task that's often underestimated and where a lot can go wrong.
This is also the case with my neighbor, who makes the same mistake every year. He starts the pump, fills the pool with water, and generously pours chlorine into it to disinfect it. A few days later, he notices that the water has turned green and cloudy, and an unpleasant odor hangs in the air.
What happened?
Adding chlorine alone won't automatically clean the water. In fact, if the pH level isn't right, the chlorine will be ineffective. Furthermore, the pump must be cleaned before filling the pool, as dirt and debris can build up in it during the winter.
So my neighbor had done everything wrong and now had to deal with a green mess. But he wouldn't be my neighbor if he hadn't found a solution.
He sought help from a pool professional and learned the importance of measuring and adjusting the pH before adding chlorine. He was also shown how to properly clean the pump and change the filter media.
Since then, my neighbor has had no more problems with his pool and can once again fully devote himself to swimming.
So, dear pool owners, when you wake your pool from hibernation, remember: measure, adjust, clean – then nothing will stand in the way of carefree bathing pleasure.
So, how can it be better?
In the fall, before winterizing your pool, it's important to treat the water and prepare it for winter. Performing these steps in the fall can save you a lot of time and effort in the spring.
One way to prepare the water for winter is to add winter care products. These help keep the water clean and prevent algae growth. A thorough cleaning of the pool and filtration system is also important in the fall.
When spring arrives, the pool needs to be thoroughly cleaned before it can be used again. This includes removing leaves and debris, cleaning the filtration system, and refilling the pool with fresh water.
To ensure that the water quality is good in spring, you should conduct a water analysis and check the water parameters. If the water parameters are not optimal, appropriate measures must be taken to improve them.
Another tip for good water quality in spring is to use pool covers in fall and winter. A good cover protects the water from contamination and prevents insects and leaves from entering the pool.
Careful preparation in the fall and a thorough cleaning in the spring are key to a clean and safe pool. With regular maintenance and water quality checks, you can enjoy your pool year-round.
Pool water green after vacation
It's a familiar situation: You return from vacation and your pool water has turned green. This is a sign that algae has grown and the water is no longer sufficiently disinfected. A quick and effective solution to make the water clear and clean again is shock chlorination.
Shock chlorination involves adding a high dose of chlorine to pool water to kill bacteria, viruses, and algae and recondition the water. It's important to check the pH of the water before shock chlorination, as a pH outside the optimal range can impair the effectiveness of the chlorine treatment.
Shock chlorination is generally recommended when the chlorine level in the pool water is below 1 ppm (mg/l). The exact amount of chlorine required for shock chlorination depends on the size of the pool and the level of contamination. It is important to carefully follow the manufacturer's instructions and not use more chlorine than recommended.
After shock chlorination, it is advisable to not use the pool for at least 24 hours and to test the water regularly to ensure that the chlorine level remains within the recommended range. It is also advisable to check the pH of the water regularly and adjust it if necessary.
Shock chlorination is a quick and effective way to treat green pool water after a vacation. However, it's important to perform regular water analyses and keep the water clean and healthy to prevent algae growth and other problems.
Pool dosing system for automatic water care
When it comes to automatic water care for your pool, a Bayrol dosing system is a highly recommended solution. Bayrol dosing systems offer an effective method for cleaning and maintaining pool water.
There are two different versions: the Bayrol Automatic Chlor pH dosing system and the salt electrolysis system Automatic Salt AS5 as a dosing system.
The Chlorine pH Dosing System is suitable for normal water and ensures that the pH and chlorine levels in the pool are automatically maintained at an optimal level.
