Pool chlorine

What is the use of pool chlorine?

Chlorine is a chemical that kills viruses and bacteria and can break down dirt. This makes it suitable as a cleaning agent, but also to keep your pool hygienic and free of harmful substances. For example, using pool chlorine prevents the growth of algae and bacterial colonies, which could harm your health. If you have a swimming pool, don't neglect the use of chlorine.

What forms can pool chlorine take?

Standard chlorine can be purchased in powder, granular and tablet form. Here you have a choice between large and small tablets. The smaller and powderier the chlorine is, the faster it will usually dissolve. Still, it's good to know that there are also fast-acting tablets and slow-acting granules. This is something you want to consider when purchasing chlorine. Slow-acting tablets are generally preferred, as they release the chlorine slowly, keeping your pool hygienically clean for longer periods of time. Granules, on the other hand, are primarily used for chlorine shock treatments.

What does a chlorine shock treatment involve?

Chlorine shock involves adding a large amount of chlorine to the water all at once, causing the chlorine level to rise very rapidly. Chlorine shock is mainly applied to pools that have just been refilled with water or whose chlorine levels have not been maintained, dropping below the desired level. If you want to perform a chlorine shock treatment, you can purchase specific chlorine products for this purpose. This is because ordinary chlorine tablets are generally slow-acting, whereas chlorine shock requires a rapid increase in chlorine concentration.

How much chlorine do you need for your pool?

When referring to a pool's desired chlorine concentration, free chlorine is actually meant. An outdoor pool should have a free chlorine content of 0.5 to 3.0 ppm (parts per mille), an indoor pool a content of 0.5 to 1.5 ppm. In practical terms, this means the following:

• 4 grams of fast-acting chlorine per 1000 liters of water
• 8 grams of slow-acting chlorine per 1000 liters of water

Is too much chlorine in the pool bad?

While too low a level of chlorine can give bacteria and other harmful organisms free rein, it is also important to prevent too high a level of chlorine in your pool. This is because if the chlorine concentration is too high, it can lead to various health issues. These include skin rashes and irritation, red or sore eyes and breathing problems. Therefore, do not exceed the recommended amount of chlorine and always follow the instructions carefully.

What should you pay attention to when using chlorine?

The proper action of chlorine depends heavily on the acidity of the water. Chlorine will not be effective unless the pH of your pool water is between 7.2 and 7.8. You can test this using a water tester. If the pH level turns out to be too high, you can use a pH-reducing product use to get it back on track.

How often should the chlorine in your pool be replenished?

How often you need to replenish the chlorine in your pool depends on the chlorine level. You can also test this using a water tester. As a general rule, you should add chlorine to your pool water about once a week to maintain the chlorine level.
