Safe™ is the complete and concentrated dry conditioner for  both fresh and salt water. Safe™ removes chlorine, chloramine and  ammonia. Safe™ converts ammonia into a safe, non-toxic form that is  readily removed by the tank’s biofilter. Safe™ may be used during tank  cycling to alleviate ammonia/nitrite toxicity. Safe™ detoxifies nitrite  and nitrate, allowing the biofilter to more efficiently remove them.  Safe™ is non-acidic and will not impact pH. Safe™ will not overactivate  skimmers. Use at start-up and whenever adding or replacing water.




NOTE: 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 in the FAQ.


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.
