How It Works:
• Breaks down chloramines into chlorine and ammonia
• Binds and detoxifies the resulting ammonia, preventing harm to fish
• Helps protect fish during tank cycling or after water changes
When to Use:
• New aquarium setup
• Routine water changes
• After adding new fish
• When ammonia or nitrite spikes occur
Directions:
• Use 5ml per 200L of new water
• Can be dosed directly to the tank, though adding to new water first is best
• For high chloramine levels, a double dose is safe
• In emergencies (e.g. high nitrite), up to 5x normal dose may be used
• If water temp exceeds 30°C, and chlorine is low, use half dose
Note: Slight sulphur smell is normal. Keep out of reach of children.
