Multilong® is the most advanced multifunctional product available! The cartridge consists of 3 x 200 g chlorine tablets, 1 x 200 g Filterclean Tab and 50 g algaecide granules with the following properties: shock disinfection of the sand filter, continuous disinfection to eliminate bacteria and turbidity in the pool water, algae prevention and flocculation.


Multilong® is a genuine multifunctional product, and the integrated filter disinfection makes it unique: The Filterclean Tab disintegrates within approx. 10 minutes and remains on the filter bed. With the circulation pump running, the granular dissolves slowly, and carries out an intensive disinfection of the filter material for about 30 minutes, safely removing dirt and bacteria. 

The algaecide granules reliably prevent algae growth. In addition, the chlorine tablets contain a flocculant to ensure crystal clear water.


Multilong® will not cause damage to the pool surface, as it does not contain copper sulfate. For more information on the usage of copper sulfate in swimming pool water, please click here.

Multilong® is ideally suitable as a holiday treatment, and treats up to 50 m³ of pool water for up to 2 weeks.
