Pool maintenance: Method and important facts
If you have your own swimming pool, you want to be able to enjoy clear, clean and bacteria-free water in the summer. To achieve this, regular maintenance is necessary. You should take the following into account:
Cleaning the pool filter

Finding the right balance with chemicals
If you want to swim in clean and bacteria-free water then you can not avoid the use of chemicals. Without the right chemicals you will very quickly suffer from algae and all kinds of unwanted bacteria. Clean water in the pool is ultimately a matter of finding the right balance between acidity (PH), hardness of the water and the amount of chlorine.
Chlorine only works well at correct PH value
Chlorine is used in swimming pool water for maintenance to kill bacteria. However, it must be dosed exactly and only works well with the correct PH value of the water. This must be neutral (7.2 is ideal). You can measure the PH value of the water yourself with digital meters or with the help of test strips. Depending on the measured value, the PH of the water can be lowered or raised with a special tool. The PH value should be measured regularly. Chlorine should be added regularly in the form of tablets (in a chlorine floater).
Pool maintenance and carbonate hardness
Fluctuations in the PH value depend on the carbonate hardness of the pool water. A hardness between 100 and 150 Ppm is fine. The harder the water, the greater its buffering capacity. In hard water the PH will fluctuate less quickly. In soft water, the PH will rise or fall faster.
Attention! Never mix different types of chlorine. This can result in unpredictable chemical reactions. Remember that you are working with chemicals and always follow the instructions on the packaging.
Add fresh water regularly
Despite the fact that the water has been treated with chlorine, substances will accumulate in the water over time. These are mainly salts formed by chemical reactions between the chlorine and nitrates in the water. You can only reduce the concentration of salts by regularly changing the water as maintenance. It is recommended to change about three to five percent of the pool water every week. In summer, the water will evaporate faster, which increases the concentration of salts. You can prevent this by covering the water if you don’t use it. An additional advantage is that no dirt can get into the water.
Preparing the swimming pool for the winter
When the water will be colder than, it is time to make the pool winter ready. First of all, you should remove any soil (sand) and floating dirt. With a
Filter and pump must be disconnected and stored frost-free. Once all this is done, the pool can be covered with a suitable winter sail. This cover should not allow light to pass through, otherwise you will still get algae growth in the winter.
Pool filled during the winter
It is best to leave the pool filled with water in the winter. The water provides counter pressure (against the walls) and the necessary weight. When the pool is empty, the ground can cause the walls to be pushed inwards. A full pool gives back pressure so this can not happen. You have to make sure that the water does not freeze. You can do this by using so-called ‘winter floats’. These are special floats that float on the water and ensure that no ice pressure will occur in freezing conditions.
