Each bottle contains 16.9 oz (500 ml) and treats a total of 5,000 gallons (20,000 L) of water. Use 1 capful (5 ml) for each 50 gallons (200 L) of new water. For smaller volumes, please note each cap thread is approximately 1 ml. May be added to aquarium directly, but better if added to new water first.
