Seachem Prime 500 ml

Directions For Use:

Use 1 capful (5 mL) for each 200 L (50 US gallons) of new aquarium water. For smaller volumes, it is important to remember that each cap thread is approximately 1 mL.The soltuion can be added to the aquarium directly, but it is significantly better if added to the new water first. If you are adding the solution directly to the aquarium, base the dose level on the aquarium volume. A sulfur odor is normal. For exceptionally high chloramine concentrations, a double dose can be used safely without harming aquatic pets. To detoxify nitrite in an emergency situation, up to 5 times normal dose may be used. If temperature shows to be > 30 °C (86 °F) and chlorine or ammonia levels are lower than normal, use a half dose.
