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.
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.

A: The directions on your package are correct for the formulation in the bottle. We have simply simplified them for the web and the formulation in our newest packaging.
A: If you are using Safe instead of Prime, you should use about 16 grams of Safe per cup of water.
A: Safe does not have the stabilizers, like Prime, to keep it stable in liquid form. We do not recommend mixing it and storing it for future use.
A: In some situations one may be aware of their exact chloramine or chlorine levels and will wish to precisely tailor the amount of Safe used. This information is provided as is and it is assumed one is sufficiently adept at the mathematics to do the proper calculations in order to determine the amount of Safe needed for a given concentration of chloramine, chorine or ammonia.
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 general formula that should help to determine the amount to use in mg for a given chloramine level is
x = L*c where x = amount to use in mg, L = volume of water (tank volume if added to tank, or source volume if water change water), c = chloramine level in mg/L (ppm). So a 500 L tank with 2.5 mg/L of chloramine would require 500 * 2.5 = 1,250 mg or 1.25 g of Safe, for gallons the formula is
x = 4*G*c (where G = gallons and 4 is a constant)
for chlorine it would be
x = 0.7*L*n where x = amount to use in mg, L = volume of water (tank volume if added to tank, or source volume if water change water). n = chlorine level in mg/L (ppm). So a 500 L tank with 2.5 mg/L of chlorine would require 500 * 2.5 * 0.7 = 875 mg, for gallons the formula is
x = 2.8*G*n (where G=gallons and 2.8 is a constant)
for ammonia it would be
x = 3*L*a where x = amount to use in mg, L = volume of water (tank volume if added to tank, or source volume if water change water). a = ammonia level in mg/L (ppm). So a 500 L tank with 2.5 mg/L of ammonia would require 500 * 2.5 * 3 = 3750 or 3.75 g for gallons the formula is
x = 12*G*n (where G=gallons and 12 is a constant)
