Kick-start your aquarium's biological filtration with Sera Filter Biostart 50ml — a highly effective bacterial starter designed to rapidly activate new and cleaned filter media for a healthier and more stable aquarium environment.
This advanced formula contains live nitrifying bacteria that quickly colonize biological filter media and begin breaking down harmful ammonium and nitrite. By accelerating the establishment of the biological filter, Sera Filter Biostart helps shorten the aquarium's cycling period and creates safer water conditions for fish.
It is ideal for new aquarium setups, after cleaning or replacing filter media, after medication treatments, or following major water changes. Regular use supports a strong biological filtration system and helps maintain long-term water quality.
