The treatment of water seems simple at first, but there are important ifferences between types of water systems. The properties of the basins are thus totally different from those of the process ater (cooling water, for example).

Green XL therefore offers a range of probiotic water treatment products adapted to the type of water to be treated. Ponds are a typical example of cases where excessive dirt and biofilm can disturb water and produce bad odors.

Ponds containing very expensive fish are often equipped with very expensive facilities whose purpose is to clean and sterilize the water. These, however, are often the cause of a very unhealthy microflora, which leads to infections in fish.

Green XL Pond Pro ensures the correct microbial composition of your pond water. This product makes it possible to rapidly overcome the biofilm which forms in the basins and which is at the origin of the turbid waters, the dirt of the filter and the pathogenic germs.

The result ? A cleaner pond with water with healthy composition.


The probiotics of the Green XL products are selected on the basis of their ability to treat organic soil and transform it into CO2 in order to clean the biofilm and dirt from the pond.

The organic dirt that accumulates in water systems ends up rotting. Some micro-organisms use it to feed themselves and turn it into malodorous gases. The probiotics of Green XL products actively absorb organic dirt and transform it into volatile compounds without odors,

The biggest problem of water systems: the excessive development of undesirable micro-organisms such as algae or cyanobacteria. They are a visual problem but can also pose a danger to the health of humans and animals. Green XL guarantee a healthy natural microflora in water systems, safe for humans and animals.

Safety and the environment

Probiotics are totally natural, therefore they contribute actively to the preservation of the environment. The probiotics used always come from earth and water, so they guarantee a natural balance.
