Shake Well. To start new aquariums, add:
- 50 ml to cycle a 20 gallon aquarium
- 100 ml to cycle a 40 gallon aquarium
- 250 ml to cycle a 100 gallon aquarium
Aquarium is then ready for fish. For healthy maintenance, add one teaspoon (5ml) for every 10 gallons when adding fish, after water changes or after replacing filter media. Each raised mark on side of bottle equals 10ml.
