What's the right amount of aquarium salt to treat ich in my fish?

Updated On September 23rd, 2025

When using aquarium salt to help treat ich how much do I use? The box says 1 teaspoon per gallon and everything that I have read says 1-5 tablespoons per gallon. I've raised my temp up to 82 so far.

If your fish are salt tolerant, use one teaspoon of plain aquarium salt per gallon of water to treat Ich. Dissolve it in a cup of tank water then pour it slowly into the tank. Increase water temperature to about 85-86 F and hold for 10 days. Vacuum the substrate once your fish lose the "dots".
