Cobalt Aquatics’ Aquarium Salt is used to help reduce stress of freshwater fish by helping fish "slime up" and replenishes natural electrolytes. It may also be used to temporarily block the toxic effects of elevated levels of nitrite in the aquarium water. Unlike table salt contains no artificial color or iodine.


For Tropical or Goldfish display aquarium, mix 1 Tbsp of Cobalt Aquarium Salt for every 5 gallons of water.

To treat your fish for external parasites (Tricodina, Ichthyobodo, or Epistylis), mix 1 to 4 Tbsp of Cobalt Aquarium Salt per gallon of dechlorinated water that is the same temperature as the aquarium. Dip the fish in the bath for 5-10 mins. When dip is completed, acclimate the fish by diluting the bath to double the original bath volume with dechlorinated water over a 2-3 minute span, then return fish to the aquarium. Bath may be repeated in 24 hours.

To treat your main Betta display aquarium, mix 1/2 Tbsp of Cobalt Aquarium Salt for every 5 gallons of water.

Stir 1 tsp Cobalt Aquarium Salt per 1 cup of dechlorinated water. Use as much water as needed to fill your shallow dish and leave in habitat. At any time, if excessive food or other waste collects in the salt bath, clean the dish, and replace the salt bath solution. Do not let bath dry out.
Be sure to remember that hermit crabs require both a freshwater supply and a salt bath. A source of fresh water is always required.
