• Suitable for cleaning filters made of stainless steel or polyester.
• Does not create foam. Produces effervescence as lime dissolves.
• Easy to apply and rinse with running water.

Dosage and instructions for use:

This treatment is only valid for filters with silex or sand filtration load.

With the filter in the off position and uncovered, drain all the water from the inside of the filter through the bottom valve.

Close the drain valve and pour 2 liters of water through the mouth of the filter followed by 2 liters of product for every 10 kilograms of sand, to cover the sand level by 20 to 30 cm.

Leave the product to react with the lime and dirt present in the filter. When the effervescence (bubbles) ceases after a preventive time (about 4 to 8 hours), close the filter cover, move the valve handle to the backwash position, and pass water through the filter to rinse it.

Stop after the preventive supervision time (about 4-8 hours), close the filter cover, move the valve handle to the backwash position, and pass water through the filter to rinse it.

The rinse water should be poured directly into the drain. During rinsing, the pH of the emerging effluent should be checked to be the same as that of the incoming water. When it reaches this point, the complete filter cleaning process can be examined.

After inspecting the filter, repeat the treatment if residues of stuck or hardened sand are found.
