Use API Aquarium Salt when setting up a freshwater aquarium or fish bowl, changing water and treating fish disease.
Add 1 rounded tablespoon for every 5 U.S. gallons (20 L), or 1/2 rounded teaspoon for every U.S. gallon (4 L) of aquarium water.
Note: Aquarium salt does not evaporate, and is not filtered out, so it should only be added with each water change. Care should be taken when using salt with live plants, as some plants may be sensitive.
Tip: Use of API Aquarium Salt is beneficial when treating fish disease, particularly parasitic infections. Symptoms of parasitic infections include: clamped fins, scratching on objects and labored breathing. For best results, use API Aquarium Salt with API General Cure™ or API Super Ick Cure™.
