While this solution is by far the most advantageous in terms of cost and efficiency, it is no less aggressive… In fact, the chlorine can make your pool water odorous and irritating, to the point of causing allergic reactions in bathers.

Fortunately, there are now alternatives to avoid these inconveniences during your swims. swimming pool salt electrolysis. More environmentally-friendly and chlorine-free, this type of treatment has the advantage of naturally disinfecting pool water, without the risk of allergies or irritation.

But what are the between these two treatments? What are the steps involved in your pool from chlorine to salt? And how much does it cost?

Find out everything you need to know below…


Advantages, disadvantages, price… Why switch from chlorinated water to salt?

The advantages of a salt pool

For pools with treatment, free chlorine (which contains active chlorine) is responsible for disinfection and elimination of various microorganisms. For salt pools, the process is not so different… once the device has been installed, salt water chlorinator converts salt into chlorine, without the need to add any chemicals. Using a small amount of salt (7 times less than seawater), electrolysis cells produce chlorine (sodium hypochlorite) and destroy all organic matter, bacteria, micro-organisms, algae and other pollutants. Once its disinfectant action is complete, the chlorine will automatically recombine into salt under the effect of UV rays. And so on…

As you can see, thanks to the partial renewal of chloride ions, very little salt is consumed!


Effective for disinfecting ponds, water treatment water treatment by salt electrolysis also provides numerous benefits for the skin. Unlike other chemicals, such as unstabilized chlorine, electrolysis doesn’t dry out the skin and even prevents the appearance of fungal infections! This is due to the fact that pool water contains less chloramines, a chemical compound that is responsible for this condition. chlorine odor characteristic with which we are all familiar. Just like seawater, psoriasis sufferers can see an improvement by switching from chlorine pool treatment to salt treatment.


Another advantage of the salt pool, and not the least, is that it’s more environmentally friendly. In fact, when you need to drain the water from your pond, it goes either into the garden soil or down the drain. Unlike chlorine or bromine, which contain polluting chemicals, pool salt does not harm the environment in your home or neighborhood.


The disadvantages of a salt pool

On the downside, pool owners are finding that salt treatment tends to raise pH levels. To avoid unpleasant surprises, it is therefore advisable to adjust the pH level regularly or to install a pH controller. pH regulator. In addition, due to the corrosive nature of salt, this type of treatment requires frequent washing of the machine. salt water chlorinatoror risk damaging it.


Cost: what about switching from chlorine to salt?

Price is also a barrier to switching from chlorine to chlorine treatment to selective electrolysis.l. Indeed, the overall cost of a salt pool is generally more important than chlorine- or bromine-treated ponds. This is due to the cost of purchasing and installing the chlorinator, which averages around €1,500. On the other hand, the daily running costs are lower; for comparison, you can find a 20 kg bag of salt for around €10. To buy chlorine, you’ll need to spend over €100 for the same quantity (the price varies according to the distributor and the technical characteristics of your pool).


How do I switch my pool from chlorine to salt?

To make the switch from chlorine to sodium chloride sodium chloride disinfection, a few precautions should be taken. The transition will have to be made in several stages.


Step 1: Removing chlorine from water

Before beginning the transition process, start by turning off the chlorine supply to your pool and leave the filtration system. Regularly monitor chlorine levels with test strips; once they’ve dropped below 1 ppm, you can move on to the next step.

To speed up chlorine elimination, choose the summer season when the sun is shining or when there’s heavy rain.


Step 2: Purge the filtration circuit and install the chlorinator

Is your pool chlorine-free? You can now purge the filtration circuit, dismantle the treatment dispenser (chlorine bleach, chlorinator, etc.) and reconnect the pipe to the dismantled dispenser.

Once this stage is complete, you can install the pool salt chlorinator. For best results, don’t hesitate to call in a pool specialist for this step.


Step 3: Calculate the amount of salt required

Your electrolyser is correctly installed in your pool, all you need to do is calculate the amount of salt required. To do this, you need to know the volume of water in the pool (A) and the operating weight of your chlorinator (B). Then the formula is simple: A x B = x kilos of salt

So if your pool has a volume of 60 cubic meters and your chlorinator operates at 4 grams of salt, you’ll need 4 * 60 = 240 kilos of salt.

Start up your chlorinator as soon as the salt has dissolved properly in the water.


Step 4: Check water pH level

As mentioned above, using salt to treat your pool treatment of your pool can raise the pH level of the water. For this reason, you’ll need to check the PH regularly to keep it between 7.2 and 7.4; for ease of use, Aboral recommends that you install a pH controllerThe pH regulator is capable of autonomously detecting and managing pH variations.


Can I use shock chlorine in a salt pool?

The answer is yes! Your pool already uses a form of chlorine as a disinfectant, so adding a chlorine-based shock treatment will have no impact on your salt pool. To do this, add chlorine pebbles or granules according to the volume of your pool.

Don’t forget to add an anti-algae product and filter your pool to completely eliminate algae and restore optimal water quality.
