A specialized formula was created for the quick and effective elimination of ammonia and nitrogen compounds from the aquarium. Bio S contains specially selected bacterial strains that create a perfect environment for replication of Nitrospirae and Nitrobacteraceae bacteria which are responsible for the nitrogen cycle. In the nitrification process, bacteria remove compounds, such as ammonia and nitrite from the water. Bio S is recommended especially in the first days after setting up a new aquarium to start and accelerate the nitrification process. Bio S is also perfect for settling up filtration media in newly established aquariums. In matured aquariums, it accelerates the decomposition of food residues, as well as other organic compounds and sediments. It improves the clarity of water and promotes cleaning the substrate. Bio S can also be used in tanks with probiotic bacteria-based filtration systems. Dosage: 1 drop per 100 l of water every day for the first 2 weeks. In the functioning aquariums, Bio S should be used after water changes. Shake before use.
