What is chlorine?

Chlorine is the ideal disinfectant for your pool. But what precisely is chlorine? And what does it do to your pool?

Free versus bound chlorine

You may encounter 2 different types of chlorine in your pool: free chlorine and bound chlorine. Together they form total chlorine.

Free chlorine is chlorine that is still active and can be used to fight dirt and bacteria. Once the free chlorine has reacted with dirt or bacteria, it becomes bound chlorine.

The free chlorine content is ideally about 1 ppm to ensure proper disinfection of the water. The total chlorine content must not exceed 3 ppm otherwise the chlorine will bleach the interior lining of your pool or destroy the pipes and fittings.

Different types of chlorine

Besides the chlorine values, different types of chlorine are available to add to your pool. You can divide chlorine into 2 types and 3 physical forms. On the one hand, there is a difference between organic and inorganic chlorine.

Organic chlorine can be found in the standard chlorine tablets and chlorine powder that can be found in all swimming pool shops. This chlorine contains cyanuric acid to ensure that the chlorine is not broken down so quickly by the sun. The disadvantage of this is that the chlorine is slightly less effective.

Inorganic chlorine is very effective chlorine that combats dirt and bacteria in the pool quickly and effectively . This chlorine must be used when your pool is fitted with an ioniser. This is because organic chlorine will cause your ioniser to rust. All HTH chlorine is inorganic and therefore suitable for an ioniser.

Liquid chlorine, tablets or powder

Swimming pool chlorine can be found in 3 different forms: liquid, in powder form (granules) or chlorine tablets. The physical differences are clear, but are there also other differences?

Liquid chlorine

Chlorine tablets

Chlorine granules

  • Always inorganic
  • Quick and direct effect on the chlorine value
  • Difficult to measure
  • Hazardous to use: follow safety instructions
  • Ideal for chlorine shock or automatic dosing system
  • Both organic and inorganic variants
  • Slowdissolving and therefore long-lasting effect
  • Ideal for weekly maintenance

 

  • Both organic and inorganic variants
  • Fastdissolving and faster effect
  • Easy to measure accurately to the gram
  • Ideal for chlorine shock

 

Chlorine tablets are also available in the form of 4-in-1 chlorine tablets. They disinfect, kill algae, act as a flocculant and make the water clearer. Ideal to add to your pool every week. So using this tablet gives you complete maintenance.

What is chlorine used for?

What is chlorine used for?

Chlorine is the disinfectant in your pool. Once your pool pH is okay, you can put chlorine in the pool to kill all the bacteria. That way you always swim in a healthy pool.

So why do you put chlorine in your pool? The reason therefore has to do with your health. Without chlorine you could get an infection much faster from bacteria in your pool.

How much chlorine should you add to your pool?

The chlorine dosage depends on many things. Normally you can find instructions for use on the back of your bucket or can of chlorine. This will help you calculate how much chlorine you need to add to the pool to get a chlorine value of 1 ppm.

With liquid chlorine it is very difficult to add the right amount of chlorine anyway. Some people add this product recklessly to the pool. We recommend that you add only half a litre at a time to a pool of 50,000 litres or more. Adding extra liquid chlorine does more harm than good.

Chlorine powder can, in principle, be added to the pool accurately to the gram. This is ideal for those who like to work precisely and correctly.

Those who use chlorine tablets usually add 1 tablet per skimmer. Once the previous tablet has completely dissolved, it is often the right time to add a new chlorine tablet. However, we recommend measuring the chlorine and adding the chlorine only when the chlorine value is lower than 1 ppm.

How much chlorine should you add to your pool?

Where can I buy chlorine?

Chlorine can be found in many shops and there are also a wide range of products available online. Nevertheless, we can give you some advice about this.

The chlorine found in a DIY store or a toy store is mainly chlorine for use in smaller toy pools or plastic pools. If you want chlorine for a pool of 30,000 litres or more, it is better to order the chlorine from a specialist pool shop.

Chlorine from a local pool builder is more effective than the chlorine from DIY stores. You can buy cheap chlorine, but the best chlorine at Swimmingpools.be or in one of our stores. Because we buy in larger quantities, we can offer the highest-quality chlorine at the best price. So at Swimmingpools.be you’re definitely at the right (web) address.

Use biocides safely. Before use, read the label and product information.
