How to Reduce Ammonia in a Fish Tank?

When starting a new fish tank, you may have come across the term “aquarium cycle,” which involves allowing Ammonia and nitrite levels to reach zero before adding fish. Although this may initially seem confusing, it is important to understand the role of Ammonia in aquatic systems and how it can impact your tank. Fortunately, microorganisms can help break down Ammonia, but additional steps such as water changes or chemical conditioners may be necessary to maintain a healthy environment for your fish. In this article, we will explain what Ammonia is, how it can affect your tank, and provide tips on preventing and addressing ammonia-related issues in freshwater and saltwater fish tanks.

Understanding Ammonia in Fish Tanks

What is Ammonia?

So, what’s the deal with ammonia? Well, it’s a nitrogen compound in fish tanks due to fish waste, leftover food, and decaying organic matter. You might not see it, but it makes its presence known with a pungent odor. Ammonia is a crafty chemical that dissolves easily in water, which can mess with the quality of the water and put our aquatic buddies at risk.

Why is Ammonia Harmful to Fish?

Fish have their way of dealing with waste, and ammonia is part of the package. In the wild, this ammonia is swiftly diluted and flushed away by the surrounding water. However, if we don’t keep things in check in our cozy fish tanks, those ammonia levels can skyrocket in no time.
Now, here’s the catch: ammonia is toxic to fish. It can harm their delicate gills, leading to respiratory problems and weakening their immune systems. Yikes! Plus, high ammonia levels can stress out our finned friends, making them lose their appetite and become more prone to diseases. No one wants that for their aquatic pals, right? That’s why it’s super important to keep a close watch on those ammonia levels and take action to keep them low for the well-being of our fish.

Partial Water Change

A partial water change is one of the simplest and most effective ways to lower ammonia levels in your aquarium. It involves changing out about 30 to 50% of the total Water in your aquarium with fresh, clean Water. The fresh Water will not have Ammonia, so it will dilute the Ammonia in your aquarium. You should do this regularly to maintain good water quality in your aquarium.

Cycle Your Tank 

If you have a new tank, there are very few chances of bacteria in your aquarium. Beneficial bacteria are the bacteria that are good for your tank and help to reduce the ammonia levels in your aquarium. You need to cycle the aquarium to increase the beneficial bacteria in your aquarium. Cycling your aquarium involves establishing the nitrogen cycle, which converts harmful Ammonia into less harmful nitrate. It can take a few weeks, but once established, it will help to maintain good water quality in your aquarium.

Improve the Filtration 

Weak filtration can also cause an increase in the ammonia level in your aquarium. There are various things you can do to improve filtration in your aquarium.

Use a Filter

 If you still need to start using a filter, use one for your aquarium. The filter will keep the Water clear and provide a place for the beneficial bacteria’s growth, which helps lower the ammonia level in your aquarium. A hang-on-the-back filter is sufficient if you have a small tank of about 20 gallons. If you have a larger tank, you should use a canister filter.

Add Another Filter

If you are using a filter for your aquarium, you should add another filter to improve the filtration. For example, if you have a large tank and use a canister filter for it, you should supplement it with another hang-on-the-back filter. It will help increase the water flow in your aquarium and provide more surface area for the beneficial bacteria to grow.

Remove Unnecessary Impurities 

Unnecessary impurities like uneaten food, dead plants, and fish cause a high ammonia level in the water tank. It can cause a rise in the ammonia level of your aquarium. If you find a lot of uneaten food in your aquarium, you should reduce the quantity of food you feed your fish. Vacuum your substrate as well, as there will be a lot of impurities trapped in it.

Lower the pH of the Water.

 Lowering the pH of the Water will not necessarily remove the Ammonia from the Water, but it will give you sufficient time to fix the problem. If you use substrates like crushed coral or coral sand, your aquarium water has high pH because it releases calcium that provokes a spike in the pH level.

Upgrade to a Bigger tank.

If your fish tank is overcrowded, it can lead to high Ammonia levels. Upgrading to a bigger tank can help dilute the ammonia levels and provide more space for your fish to swim and grow.

Keep Live Plants in the Aquarium

Live plants can be a natural way to reduce ammonia levels in your aquarium. The plants absorb the waste your fish produces and use it as a fertilizer for their growth. Additionally, the plants release oxygen, which is beneficial for the fish.

Add Beneficial Bacteria

Beneficial bacteria are crucial in maintaining a healthy environment in your fish tank. If your aquarium is new, it may need more beneficial bacteria to convert the Ammonia into a less harmful form. Adding gravel or filter pads from an established aquarium can introduce beneficial bacteria to your tank.

Preserve the Beneficial

Bacteria Cleaning your aquarium substrate and filter with tap water can remove the beneficial bacteria from your tank. Instead, clean them using aquarium water to preserve the bacteria. This way, the beneficial bacteria can continue to convert the Ammonia into a less harmful form and maintain a healthy environment for your fish.

Causes of Ammonia in a fish tank:

Maintaining a healthy environment for your fish is crucial for their well-being, and ammonia levels in a fish tank can harm their health. Ammonia is a toxic compound that can build up in aquarium water and harm the fish, causing stress and even death. Following are the causes that trigger Ammonia:

• Unnecessary waste like dead plants, fish, and uneaten food produces Ammonia in a fish tank.
• Overstocking, where too many fish are in a small tank, can also cause high ammonia levels.
• Bad filtration can lead to a build-up of Ammonia.
• Low amounts of beneficial bacteria in the aquarium can also result in high ammonia levels.
• High water pH, often caused by coral sand or crushed coral substrate, can also contribute to high ammonia levels.
• Not cycling the aquarium before adding fish can lead to a lack of beneficial bacteria to remove Ammonia.

Conclusion: How to Reduce Ammonia in a Fish Tank?

Keeping the ammonia levels low in your fish tank is essential for the health and well-being of your fish. High Ammonia levels can be toxic and cause various health issues for your aquatic pets. Regular water changes, proper feeding, using a filter, upgrading to a bigger tank, adding live plants, and preserving beneficial bacteria are effective ways to control and reduce ammonia levels in your fish tank. It is important to note that monitoring the water parameters of your aquarium regularly is crucial to ensure the overall health of your fish. A healthy and clean environment ensures that your fish remain healthy, happy, and thriving.
