Why do people put chlorine in pools

ph value as a warning signal How to avoid germs in the paddling pool

It is best to fill mini pools with fresh water every day

Experts, such as the microbiologist Prof. Dirk Bockmühl, advise against treating the water in smaller paddling pools with chlorine or other chemical products. There is a risk that the additives cannot be dosed correctly due to the small amount of water, and the plastic walls of the pools can also be attacked. They therefore recommend emptying the mini paddling pools every evening and filling them with fresh water the next day:

Tip: The water can be used to water flowers.

Hygiene tips for larger paddling pools and pools

There are essentially two values ​​that indicate whether your pool water is perfectly prepared: the pH and the chlorine value. To determine the values, there are test strips and devices, for example in hardware stores.

Ideal pH between 7.0 and 7.4

The most important thing in water maintenance is pH. It influences all factors of the pool water and should ideally be between 7.0 and 7.4. Outside of this range, it can happen, for example, that added chemicals such as chlorine have less of an effect. Furthermore, if the pH value is too high, the skin leaches out and if the pH value is too low, skin reddening occurs.

As a rule, the measured pH value will be above the ideal, i.e. it will tend to be more basic. The value can be lowered by adding a pH reducer, usually offered as granules. If the pH value is too low, use a so-called pH lifter. Pay attention to the manufacturer's instructions for both so that you do not overdose.

Tip: Dissolve the preparations in a little water before you put them in the pool, so they will distribute better and more evenly.

Chlorine as a disinfectant

Chlorine is a disinfectant that not only kills bacteria and germs, but also inhibits the formation of algae. The chlorine content per liter of water should be around 0.3 to 0.8.0 mg, some experts limit this further and recommend a value between 0.4 and 0.6.

Chlorine is available in different tablet sizes. The tablets are placed in so-called floats. From there, the chlorine gradually gets into the water. Liquid chlorine is used for automatic dosing in larger pools. And special, quick-dissolving chlorine products are used for so-called shock chlorination in the event of severe cloudiness or algae growth. So think carefully about what you want to use the chlorine for and pay attention to the manufacturer's instructions, because too much chlorine can cause eye irritation or even conjunctivitis.

Choir is poisonous: So it shouldn't get into children's hands and the little ones shouldn't play with the swimmers either!

By the way: Chlorine is odorless. Only the reaction with other substances leads to the typical chlorine odor.

Sand filter systems - a worthwhile investment

In addition, a sand filter system for the home pool makes sense. Not only algae and dirt particles stick to the quartz sand, but also bacteria. At around 100 euros, the sand filter system often costs more than the entire pool, but the water stays clean longer and you save costs.

Regular fresh water supply

The pool continuously loses water through evaporation and splashing. That should be refilled. And before you completely replace the water in the pool, replacing just a part can significantly improve the water quality.

Shower and walk-through basin

The pool goers carry a lot of debris into the pool. But that can be significantly reduced with a few simple measures. Just like in the swimming pool, it is ideal to shower the body beforehand, so sweat and cosmetics stay away from the water.

If you then place a walk-through pool in front of the pool, for example a small tub with water, you ensure that only clean feet get into the pool.

Other useful utensils for pool maintenance

Pool broom: So that nothing settles on the floor, you should regularly sweep the ground with a pool broom. Fine algae are swirled in the direction of the filter. If you don't have a filter, you can collect coarse debris with the net.

Landing net: Leaves, dust, insects and other coarse dirt should be removed from the water surface daily with a net.

Tarpaulin: At night or when the pool is not used for a long time, a tarpaulin helps to protect it from coarse contamination. In doing so, you are also doing the wildlife a favor, because many animals drown miserably in the pools because they no longer have the opportunity to get on land.
