How does a whirlpool clean the water

What you should know about hot tub maintenance

Most important purity law: personal hygiene

Pollen, dust, urea, hair or flakes of skin - all things that you certainly do not want to have in your hot tub. After all, healthy and clean hot tub water is essential for relaxing moments in your small spa. Considerate and experienced spa users should therefore observe a few small rules before getting into the water.

The most important basic rules for your own personal whirlpool purity law:

  • Take a good showerbefore entering the bubbling water. Pollen, dust, flakes and other unwanted particles are rinsed off beforehand and do not even get into the whirlpool.
  • Also, rinse your swimwear with clean water - especially if you have previously washed them in the washing machine. Detergent residue can cause the spa water to foam. The same goes for shampoo residue in your hair.
  • You should also avoid hairspray, creams, sunscreen and other cosmetics before going into the whirlpool.

Water care & water treatment

However, even the most meticulous personal hygiene and compliance with the whirlpool purity law cannot prevent the water from becoming contaminated or otherwise changing. To prevent this, regular water maintenance and water treatment are essential.

Covers to protect against environmental influences

A good start is to use a cover. Regardless of whether it is an indoor or outdoor whirlpool - when the device is not in use, such a custom-made cover protects against the water Leaves, rain and dirt particles. It also prevents animals from getting lost in the pool and additionally contaminating it.

Regulate water hardness for water balance

In addition, pay attention to the water balance. Measuring devices give you information about the various values ​​and inform you when you need to intervene. First of all, the calcium and carbonate hardness are important Your tap water. The water hardness can vary between 4 and 20 German degrees of hardness (dH), but is normally in the range between 12 and 20 dH. The more the calcium and magnesium particles are concentrated in the water (calcium hardness), the higher the risk of calcium deposits. On the other hand, if the carbonate hardness is too low, pH fluctuations can occur. You can counteract this by increasing the alkalinity.

Do not use softened water for your whirlpool!

Use measuring devices or measuring sticksto keep a constant eye on the important pH value of your hot tub water. This value, given in parts per million (ppm), changes constantly - too great deviations from the ideal value (7.6 ppm) lead to either basic (value above 7.8 ppm) or acidic water (value below 7.2 ppm). Both have a negative effect on the water quality.

Acid and alkaline water - the ideal pH value

While acidic water likes to attack the surface and sensitive technology of the whirlpool, alkaline water can die irritate human mucous membranes with chloramine. In addition, the latter quickly forms foam and lime. Due to the oxygen, metal parts oxidize faster and rust occurs. In addition, agents for disinfecting can no longer develop their full effect in the water.

You can bring acidic water back into the desired equilibrium with a pH booster and alkaline water with a pH reducer.

Disinfection: chlorine, oxygen or bromine?

Your whirlpool water is usually disinfected according to the same principle as in swimming pools: by the Addition of chlorine. If you have filled your whirlpool with water for the first time, it makes sense to disinfect it for the first time. Add two tablespoons of granulated chlorine to kill microorganisms and remove contaminants. This is followed by constant disinfection by means of slowly dissolving Chlorine tablets in the dispenser or compartment provided for this purpose. If you should forget to refill the chlorine tablet compartment, use chlorine granules to clean the water that has already become cloudy.

After using the whirlpool several times, the typical acrid and eye-irritating smell of chlorine often occurs. This occurs when chlorine binds with fats, lotions, oils and dirt particles. The resulting waste product is called chloramine.

If the smell of chlorine is too strong, carry out what is known as shock chlorination once a week by adding ten times the amount of chlorine.

It doesn't always have to be chlorine: An alternative is oxygen. However, this method is considered twice as expensive. You can get other chlorine-free water care products that are organic. On the other hand, bromine as an alternative disinfectant is not suitable as a usable substitute for chlorine due to its restrictions on hazardous goods.
