Chlorine-Away is a product commonly used in aquariums to neutralize chlorine and chloramine in tap water. These chemicals are often present in municipal water supplies to kill harmful bacteria, but they can be toxic to fish and other aquatic life. By using Chlorine-Away, you can make tap water safe for your aquarium inhabitants.

Here's how you typically use Chlorine-Away in your aquarium:

1. Dosage: Follow the instructions on the product label to determine the correct amount to use. This usually depends on the volume of water being treated.

2. Application: Add the appropriate amount of Chlorine-Away to the tap water before adding it to your aquarium. Some people add it directly to the aquarium when doing water changes.

3. Mixing: Stir or agitate the water to ensure the product is evenly distributed.

4. Wait Time: Wait for a few minutes to ensure the chlorine and chloramine are neutralized before adding the water to the aquarium.

Always ensure you're using the correct dosage and follow the manufacturer's guidelines to avoid any potential harm to your aquarium's ecosystem.
