How do I choose my chlorine?

Choosing the ideal chlorine for your pool

Disinfecting pool water is crucial for a healthy and enjoyable swim. Chlorine is one of the most popular disinfectants, but knowing which type to choose can be confusing. Here's a guide to help you navigate the options.

Chlorine tablets

Use: Chlorine tablets are ideal for slow, even diffusion. They are usually placed in skimmers or a floating diffuser and are suitable for in-ground or above-ground pools.

Benefits :

• Ease of use
• Gradual dissolution for consistent treatment

Disadvantages:

• May increase the level of stabilizer (cyanuric acid) in water

Powdered chlorine (shock chlorine)

Use: Ideal for intensive treatments, powdered chlorine is used to quickly increase the chlorine level, particularly after heavy rain or intensive use of the pool.

Benefits :

• Fast and effective action
• Suitable for emergency treatments

Disadvantages:

• Requires precise dosage
• May also contribute to increased stabilizer in water

Liquid chlorine

Use: Liquid chlorine is often used with dosing pumps or chlorine regulators. It is suitable for in-ground pools equipped with these systems.

Benefits :

• No increase in stabilizer in water
• Easy to dose with measuring systems

Disadvantages:

• Requires proper storage to avoid degradation

Chlorine without stabilizer

Use: An option for pools where the stabilizer level is already high. This type of chlorine acts as an oxidant to remove contaminants without increasing the stabilizer.

Caution! Never mix stabilized and unstabilized chlorine!

Benefits :

• Does not compromise water disinfection
• Does not increase the stabilizer rate

Disadvantages:

• May require more frequent adjustment of chlorine level

Tips for choosing chlorine

• Vary the types of chlorine to avoid saturation by stabilizer.
• Monitor the stabilizer level ; the limit is 75 mg per liter of water. Beyond this, you will need to renew some of the water.
• Green water doesn't always indicate a lack of chlorine. Too much stabilizer can render chlorine ineffective.

In summary, the choice of chlorine depends on your pool type, your filtration system, and your personal preferences. Consider this information to select the chlorine that will ensure clean and safe pool water.
