Bacterial supplement designed to quickly establish and support a healthy aquarium biofilter. Shake well before use and switch off UV or ozone during application. Dose 5 mL per 40 L for initial use, followed by 5 mL per 80 L as maintenance when adding livestock or after biofilter disruption. Remove antibiotics with fresh carbon and a water change before dosing, and allow 2–3 days for bacteria to establish before restarting UV or ozone.
