To increase ammonia in an aquarium, especially when cycling a new tank without fish, you can introduce a source of ammonia into the water. A direct method is to add pure ammonia.
Methods to Introduce Ammonia
Increasing ammonia levels is typically done when establishing the nitrogen cycle in a new aquarium, a process known as 'fishless cycling'. This provides the necessary food source for beneficial bacteria to grow. Here are common ways to achieve this:
Using Pure Ammonia
Instead of relying on decaying organic matter like fish food, pure ammonia can be added directly to the tank water. This method offers precise control over the ammonia level.
- How to Apply: According to one method, after your tank is set up, add five drops of pure ammonia per ten gallons into the water on a daily basis.
- Goal: Continue this daily addition until the ammonia concentration consistently rises to five ppm (parts per million) and higher. This high level ensures a robust food source for the nitrifying bacteria you are trying to cultivate.
- Type of Ammonia: Ensure you use pure ammonia (ammonium hydroxide) that is free from surfactants, dyes, or perfumes. Shake the bottle; if it produces lasting bubbles, it likely contains surfactants and is unsuitable for your aquarium.
Adding Fish Food or Decaying Organic Matter
Another common technique is to add a small amount of fish food to the empty tank. As the food decomposes, it releases ammonia.
- Process: Sprinkle a pinch of fish food into the water daily or every other day.
- Monitoring: Test the water regularly to monitor the ammonia levels.
- Considerations: This method can be less precise than using pure ammonia, and the decomposition process can take time.
Using Ammonia Chloride Products
Commercial products containing ammonia chloride are specifically designed for aquarium cycling.
- Ease of Use: These products often come with dosing instructions based on tank volume, making it straightforward to add a controlled amount of ammonia.
Why Increase Ammonia?
Increasing ammonia is a crucial step in the aquarium cycling process. This process establishes a colony of beneficial bacteria (Nitrosomonas and Nitrobacter species) that convert toxic ammonia into nitrite, and then into less toxic nitrate. A stable nitrogen cycle is essential for the health and survival of fish and other aquatic life.
| Method | Precision | Speed | Typical Use | Notes |
|---|---|---|---|---|
| Pure Ammonia | High | Moderate | Fishless Cycling | Requires pure, additive-free ammonia |
| Fish Food | Low | Slower | Fishless Cycling | Less control over ammonia levels |
| Ammonia Chloride | High | Moderate | Fishless Cycling | Products formulated for aquariums are ideal |
By using one of these methods, you can effectively raise ammonia levels in your aquarium to initiate and complete the nitrogen cycle before adding livestock.
