Info: Seachem 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.
