Safe is the complete and super-concentrated dry conditioner for both fresh and saltwater. Safe removes chlorine, chloramine and detoxifies ammonia, nitrite, and nitrate. It is non-acidic and will not impact pH. A further bonus for the reef hobbyist—Safe will not over-activate skimmers.
Safe may be used during tank cycling to alleviate ammonia/nitrite toxicity. It contains a binder that renders ammonia, nitrite, and nitrate non-toxic, allowing the biofilter to more efficiently remove them. Use at start-up and whenever adding or replacing water. When transporting or quarantining fish, use Seachem StressGuard. When adding new fish, use Stability. Both are ideal for use with Safe.
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.
NOTE: These directions supersede all other prior packaging.
It may be added to the 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 the normal dose may be used. If the temperature is > 30 °C (86 °F) and chlorine or ammonia levels are low, use a half dose.
