API Aquarium Salt, made from evaporated sea salt, is a must-have for your aquarium! Aquarium salt promotes fish health by improving gill function, making it easier for fish to breathe. It also provides essential electrolytes that fish need to reach peak coloration and vitality. These electrolytes may be lost each time you perform a partial water change, and will need to be replenished with API Aquarium Salt. Use API Aquarium Salt in freshwater aquarium tanks when starting a new aquarium, and any time you perform a water change. Care should be taken when using salt in aquariums with live plants, as some plants may be sensitive.

DIRECTIONS FOR USE: Add 1 rounded tablespoon for every 5 gallons or 0.5 teaspoon for every gallon of aquarium water.

Two things worth knowing before you use it. Salt does not evaporate and is not taken out by the filter, so the only thing that removes it is a water change — top-ups do not dilute it, and re-dosing without accounting for what is already in there stacks up. Replace it in proportion to the water you actually change.

And API’s own caution: take care with live plants, some of which are sensitive to salt. API position it as a stress reducer during setup, water changes and recovery — not as a treatment for disease on its own.
