Granular chlorine for swimming pools

Granular pool chlorine is one of the most effective and widely used treatments for quickly and safely disinfecting pool water. Thanks to its fast dissolution and strong oxidizing power, it is ideal for shock treatments and intensive maintenance.

At Mercapool, you will find different types of granular chlorine adapted to every pool maintenance need.

What is granular chlorine?

Granular chlorine is a chemical disinfectant designed to eliminate bacteria, microorganisms, algae, and organic matter present in swimming pool water.

Its granular format allows rapid dissolution and immediate action in the water.

Types of granular chlorine for pools

Dichlor granular chlorine

Dichlor granular chlorine stands out for its rapid action and high solubility. It is ideal for shock treatments and regular maintenance.

Trichlor granular chlorine

Trichlor granular chlorine provides a slower and more stable chlorine release, helping maintain consistent disinfection levels.

Advantages of granular chlorine

  • Fast action: ideal for restoring cloudy or green pool water.
  • Powerful disinfection: eliminates bacteria and algae.
  • Easy application: simple to dose and use.
  • Compatible with most pool types: above-ground and in-ground pools.
  • Perfect for shock treatments: especially after storms or heavy pool use.

When should granular chlorine be used?

Granular chlorine is especially recommended in situations such as:

  • Pool start-up at the beginning of the season.
  • Recovery of green or cloudy water.
  • Weekly shock treatments.
  • After heavy rain or storms.
  • Periods of high swimmer activity.

How to properly apply granular chlorine

  1. Check the pool water pH level beforehand.
  2. Dissolve the recommended amount of product in a container with water.
  3. Apply the mixture evenly around the pool.
  4. Keep the filtration system running for several hours.
  5. Wait the recommended time before swimming.

Always follow the manufacturer’s instructions and adjust the dosage according to the pool water volume.
