Info: Safe Dosing Instructions

These directions supersede all other prior packaging.

The standard dose of 100 mg/100 L of water will remove 1 mg/L (ppm) of chloramine, 1.4 mg/L (ppm) of chlorine and 0.33 mg/L (ppm) of ammonia. A formula to determine the amount to use in mg for a given chloramine level can be found below in red.

50 g

Use 200 mg Safe (scoop) per each 200 L (50 gallons) as needed to reduce chlorine and chloramine or per 50 L (13 gallons) for ammonia.

All other sizes

Use 1.25 g (1/4 tsp.) for every 1,250 L (300 US gallons) as needed to reduce chlorine and chloramine or use 1.25 g (1/4 tsp.) for every 300 L (75 US gallons) for ammonia. For precise dosing, use the Seachem Digital Spoon Scale.

May be added to aquarium directly, but better if added to new water first. If adding directly to aquarium, base dose on aquarium volume. For exceptionally high chloramine concentrations, a double dose may be used safely. To detoxify nitrite and nitrate in an emergency, up to 4 times normal dose may be used. If temperature is > 30 °C (86 °F) and chlorine or ammonia levels are low, use a half dose.
