Which Morton products can be added directly to a salt water aquarium?
For salt water fish, Morton recommends using commercially prepared seawater (marine) mixtures, as they should contain the proper ratio of trace minerals. Morton does not make a product specific for salt water aquariums. Morton® White Crystal® Solar Salt is not a sea salt obtained from evaporation of ocean water to dryness. It is a higher purity salt, and therefore cannot be used to make seawater for salt water fish without additional trace mineral supplementation. Please consult your fish expert or veterinarian for the proper use of salt in a pond or aquarium.
