A water dechlorinator is a liquid or tablet treatment used in aquariums to neutralize harmful chlorine and chloramine present in tap water, making it safe for fish, plants, and beneficial bacteria. These chemicals are often added to municipal water supplies to kill bacteria but can be toxic to aquatic life.
Key Functions of a Water Dechlorinator:
- Neutralizes Chlorine: Converts chlorine into harmless chloride, which is safe for fish and plants.
- Breaks Down Chloramine: Splits chloramine (a compound of chlorine and ammonia) and detoxifies the resulting ammonia.
- Protects Fish: Some products also include ingredients to detoxify heavy metals and add a protective slime coat to fish.
When to Use It:
- Setting Up a New Tank: Treat tap water before adding it to the aquarium.
- Water Changes: Use it during every partial water change to ensure fresh tap water is safe.
- Emergencies: For accidental exposure to untreated tap water or during ammonia spikes (for multi-function dechlorinators).
Types of Dechlorinators:
- Basic Dechlorinators: Neutralize chlorine and chloramine.
- All-in-One Conditioners: Also detoxify heavy metals, ammonia, and nitrite, and may contain stress reducers for fish.
Application:
- Follow the dosage instructions on the product label.
- Add it to the new water before introducing it to the tank.
