Aquarium Salt is a useful remedy for the prevention and treatment of several freshwater fish diseases.
When to Use Salt:
- Nitrite Poisoning: The addition of a one level Tablespoon of salt per approxamately four liters of freshwater (= 0.3% salinity) is beneficial for preventing nitrite from poisoning your fish in a newly set up tank.
- Parasites: Many external parasites can be effectively reduced with the use of salt, particularly Costia (Ichthyobodo) infestations.
When to Avoid Salt:
- Live plants: If you have live plants in your aquarium, avoid using too much salt. A relatively low dosage of salt can damage plants. Which is one reason it’s best to treat sick fish in a dedicated hospital tank rather than your regular aquarium.
- Scaleless fish: Scaleless fish species do not have the added barrier that scales provide, so they cannot tolerate much salt. The Corydoras catfish are particularly sensitive to salt; as are Tetras. Salt use in aquariums with these species should be no more than 1 level teaspoon per approxamately four liters of water (= 0.1% salinity).
Always pre-dissolve aquarium salt in water before adding to the aquarium.
