Description
API Quick Start 237ml
API Quick Start 237ml is a nitrifying bacterial treatment designed to allow immediate addition of fish when setting up a new freshwater or saltwater aquarium. Formulated with patented live nitrifying bacteria, Quick Start instantly converts toxic ammonia into nitrite and then into non-toxic nitrate, preventing “New Tank Syndrome” and toxic parameter spikes. It stabilises the biological filter during setup, after medicine treatments, or whenever new livestock is introduced into an existing setup.
