A newly installed aquarium with clean filter media is almost sterile. Without active help, it can take several weeks before a stable bacterial fauna develops, which leads to the formation and proliferation of substances harmful to aquarium life, such as ammonia and nitrites, which are fatal to fish. Haquoss DM2 ALIVE is a high-performance concentrated mixed culture consisting of selected cleaning elements that act immediately after being placed in the aquarium where the decomposition of harmful substances begins. The elements present eliminate the ammonia and nitrites produced by the fish and decompose the sludge reducing it where it exists (on the bottom and in the filter), thanks to the enzymes of which they are composed. Other elements contained in the product eliminate plant and food residues, fish excrement and organic clouding agents. Enhances the self-cleaning ability of all freshwater and saltwater aquariums by optimizing water clarity and reducing stress.
