SUBSTRATpro
The best biological filtration.
SUBSTRATpro offers optimum colonization conditions to as many purification bacteria as possible.
Due to its pearl-shaped structure, the bulk density of SUBSTRATpro is very high and it is nonabrasive. The filter volume is used to its fullest extent and no useless empty areas are formed, in which filtration cannot take place. The macropore structure of the SUBSTRATpro balls is designed so that the important purification bacteria find large, easily colonisable areas.
