The Gre brand grain chlorine is a product that dissolves very quickly and is effective in killing those dangerous fungi, microorganisms and bacteria that live in the water. This product is made up of 55% minimum active chlorine. The correct application form is diluted in water and poured directly into the pool.


The main advantage of granulated shock chlorine is that it allows superchlorination to be able to recover the water when a correct treatment has not been carried out or due to the influx of a large number of bathers or due to adverse weather conditions.

When applied already dissolved directly to the water of your pool, it favors the speed of disinfection action. We recommend that you apply this product with the treatment plant running and at night, when you know that no one else is going to bathe. It is very important to follow the instructions for a correct dosage and check the chlorine and pH values.

How to use:

• Initial treatment: add 15 grams for each cubic meter of water.
• Maintenance: with the pH of the water adjusted, add 1 to 3 grams per cubic meter of water every day.
• Introduce the daily dose inside any skimmer and start the filtration system. The dose can also be distributed equally over the surface of the pool, using a container to mix the product with water for better dissolution.
• Residual chlorine values should be between 0.5 and 2 milligrams per liter.
• Avoid using it on pools made of polyester, liner, vinyl or painted, as this product discolors them.
