Tetra Lifeguard is a broad-spectrum, non-antibiotic agent treats the clinical signs of disease at their earliest stages in freshwater fish. You don't have to be a fish expert to use Lifeguard. With this all-in-one treatment, there's no need for time-consuming guesswork. Each pre-measured Fizz Tab dose treats for disease-causing organisms associated with fungus, ick, red streaks, milky or shedding slime, flukes, bacterial gill disease, mouth and fin rot, clamped or torn fins, and ulcers. Tetra Lifeguard can also be used as a preventive when adding new fish. To treat, leave filter system operating normally; remove filter carbon for the duration of treatment. Turn off UV sterilizer if present. Add one tablet per day to each 5 gallons (19 L) of aquarium water. Treat for five consecutive days, at 24-hour intervals. For best results, after five-day treatment, wait another 24 hours (day 6) before returning activated carbon and turning on UV sterilizer.
