Dennerle Bacto Elixier FB7 BiActive is a highly active, concentrated blend of selected live beneficial bacteria for every type of aquarium.
The nitrifying bacteria remove dangerous ammonia and nitrite salts that are harmful to fish. The decomposers it also contains reduce organic sludge at the bottom of the aquarium and in the filter with the help of hydrolytic enzymes. Other types of bacteria contained in FB7 BiActive feed on plant residues and food leftovers, fish extracts, and organic suspended substances. FB7 BiActive enhances the self-cleaning abilities of all freshwater aquariums and helps the water stay cleaner.
