TankFirst helps in unusual situations such as overcrowding or overfeeding by binding with ammonia and nitrite making them non-toxic to aquatic life for up to 24 hours, until the aquarium's biological filter catches up and/or a partial water change is completed.

*Measurement using bottle cap

Add 1 Capful (5mL) for each 10 gallons of new water.

*Instructions to treat high levels of Ammonia

Be sure to reduce feeding until ammonia and nitrite is no longer present and any dead livestock are removed. If high levels of ammonia and nitrite are not the result of the initial nitrogen cycle, it is best to reduce the levels through a partial water change and use TankFirst as directed.

1. Test ammonia with an ammonia salicylate reagent test kit rather than Nessler's reagent to get an accurate reading of amount of ammonia present in water.

2. Add 5 ml (1 capful) per 10 gallons of water to treat entire system for each 1 ppm of ammonia or nitrite measured on test kit. Keep pumps and filters running.

3. Wait 10 minutes; re-test ammonia concentration in aquarium water and repeat treatment if needed.

4. TankFirst can be safely re-dosed every 24 hours.
