Things You'll Need
- Aquarium salt
- Teaspoon
Instructions
Determine the ratio of aquarium salt to the amount of water in your tank. Add one teaspoon of aquarium salt for every 10 gallons of freshwater in your tank.
Use a teaspoon to measure and pour the aquarium salt into the freshwater tank. If your aquarium holds 10 gallons, only one teaspoon is needed. If your aquarium holds thirty gallons of water, add three teaspoons of aquarium salt.
Allow the tank to sit and cycle for a few days to let the salt and calcium levels increase in the water.
