Things You'll Need
- Aquarium
- Powerhead or airstone
- Purified water
Instructions
Fill your aquarium with purified water, which you can buy at a grocery store.
Follow the package instructions and measure the salt according to how much water you have in your tank; for Instant Ocean Sea Salt, it is about 5 ounces of salt per gallon of water. Pour the salt into the water.
Let the salt gradually mix into the water overnight using a powerhead--a submersible water pump--or an airstone, which circulates oxygen by releasing small bubbles, allowing the carbon dioxide in the aquarium water to reach equilibrium with the carbon dioxide in the atmosphere and normalizing levels of pH, or acidity.
