Pool chlorine: clean and disinfected water

Pool chlorine is the most widely used disinfection system for keeping pool water clean, crystal clear, and free from bacteria, algae, and microorganisms. Thanks to its high effectiveness, it remains the preferred solution for both private and public swimming pools.

At Mercapool, you will find a wide variety of chlorine products adapted to different pool maintenance and water treatment needs.

What is chlorine used for in a swimming pool?

Chlorine acts as a disinfectant by eliminating microorganisms, bacteria, and organic matter present in the water. It also helps prevent algae growth and keeps the water in optimal swimming conditions.

Maintaining the correct chlorine level is essential to ensure pool hygiene and swimmer safety.

Types of pool chlorine

Chlorine tablets

The most common format for continuous pool maintenance. Chlorine tablets dissolve slowly, providing constant disinfection.

Granular chlorine

Ideal for shock treatments and recovering green or poorly sanitized pool water.

Liquid chlorine

Widely used in automatic pool systems and professional dosing installations.

Multifunction chlorine

Combines disinfection, algae prevention, and flocculant action in a single product for easier pool maintenance.

Advantages of chlorine pool treatment

  • Highly effective disinfection: eliminates bacteria and microorganisms.
  • Crystal-clear water: keeps the pool clean and transparent.
  • Easy application: available in different formats for every need.
  • Compatible with all pool types: above-ground, in-ground, and spas.
  • Wide variety of treatments: daily maintenance and shock treatments.

How to maintain the correct chlorine level

For proper maintenance, it is important to regularly check chlorine and pH levels in the water.

  • Recommended chlorine level: between 1 and 3 ppm.
  • Recommended pH level: between 7.2 and 7.6.

Excess chlorine may cause irritation to the eyes and skin, while low chlorine levels reduce the water’s disinfecting capability.

Chlorine shock treatments

Shock chlorine treatments are used to quickly recover water quality after intensive use, rain, high temperatures, or algae growth.

This type of treatment temporarily increases chlorine concentration to eliminate contaminants and restore water quality.

Accessories and complementary products

At Mercapool, you will also find complementary products for pool maintenance:

  • Chlorine dispensers.
  • Water testing kits.
  • pH regulators.
  • Algaecides and flocculants.
  • Automatic dosing systems.
