How to Reduce High Ammonia in Fish Tank

Maintaining a healthy environment for your aquatic pets is essential to their well-being and longevity. In an aquarium that is not properly established or maintained, ammonia can accumulate and reach harmful levels for fish.

Ammonia in a fish tank

Ammonia is a toxic substance that is released by fish waste and decaying matter, it can be detrimental to the health of fish. The main sources of ammonia are fish waste, uneaten food, and decaying organic matter such as dead plants or fish. Ammonia is produced through the breakdown of these organic substances by bacteria.

In a healthy aquarium, beneficial bacteria called nitrifying bacteria convert the toxic ammonia into less harmful substances, through a process known as the nitrogen cycle. Initially, ammonia is converted into nitrite (NO2-) by bacteria called Nitrosomonas. But Nitrite is still toxic to fish, so another group of bacteria called Nitrobacter converts it into nitrate (NO3-), which is less harmful to fish in low to moderate concentrations. Nitrate can be removed from the water through regular water changes or live plants that can use it as a nutrient.

What causes ammonia in the fish tank

Ammonia spike can happen due to various reasons below:

Overstocking: Having too many fish can overload the biological filtration capacity, leading to excess ammonia production in the tank.

Overfeeding: Feeding fish more than they can consume within a few minutes can result in uneaten food sinking to the bottom and decomposing, releasing ammonia into the water.

Poor filtration: If the aquarium filter is not properly sized or functioning, it may not be able to handle the biological load, allowing ammonia to accumulate to a spike.

Lack of maintenance: Infrequent water changes or failure to remove decaying organic matter can lead to ammonia build-up.

New tank syndrome: When setting up a new aquarium, the beneficial bacteria that convert ammonia to nitrite and nitrate need time to establish. During this initial phase, ammonia levels may rise until the bacterial colonies have grown sufficiently.

Now, let's explore effective strategies to reduce high ammonia levels in fish tanks, and promote a safe and thriving habitat for your underwater world.

Regular water changes

One of the simplest yet most effective ways to reduce high ammonia levels in tanks is through water changes.

Aim to change approximately 25% of the tank water every one to two weeks, depending on the size and stocking level of your aquarium. Use a siphon or a gravel vacuum to remove any uneaten food, fish waste, and debris. Then, replace the removed water with dechlorinated water that matches the temperature and pH of the tank.

Make a feeding schedule

Overfeeding your fish can lead to excessive ammonia production, so it is crucial to feed your fish the appropriate amount of food, ensuring they consume everything within 2-3 minutes. The uneaten food will decompose and contribute to ammonia levels. You should consider a feeding schedule that involves small, frequent meals rather than a single large feeding. This approach minimizes leftover food and reduces the potential for ammonia spikes.

Install a quality filter

An aquarium filter is essential for maintaining water quality in your fish tank. Ammonia is converted into less harmful substances through the nitrogen cycle, primarily performed by beneficial bacteria residing in the filter media. Ensure that the hygger filter is properly sized for your tank and it is clean and replaced regularly. If necessary, consider upgrading to a more efficient filter that provides adequate mechanical, chemical, and biological filtration.

Establish a balanced Bioload

The bioload refers to the total amount of waste produced by the fish and other inhabitants in the tank. Overstocking can overwhelm the biological filtration capacity of your aquarium, leading to increased ammonia levels. Ensure your tank size and filtration system can accommodate them appropriately. It is better to understock your tank and provide a healthier environment for your fish.

Introduce live plants

Aquatic plants offer numerous benefits. Consider adding live plants to your aquarium to help reduce ammonia levels. Plants also provide additional oxygen, shelter, and aesthetic appeal to your tank.

Test and monitor Ammonia levels

Monitoring ammonia levels in the tank is crucial to ensure the health of the fish. Regularly testing in your aquarium using a water testing kit allows you to identify any fluctuations or Ammonia spikes promptly. Maintain ammonia levels below 0.25 ppm, as even low concentrations can stress fish and compromise their immune systems. Monitoring ammonia levels will help you take immediate action and prevent any long-term negative effects on your fish. 

By following these strategies, you can effectively reduce high ammonia levels in fish tanks, and provide a healthier and safer environment for aquatic pets. Prevention is the key, so maintaining good water quality through regular maintenance practices is vital.

Should I Turn My Aquarium Light Off at Night?

Image
Home from work, turn off the lights, the whole person into the dark blue sofa, the color of the sofa and the same seawater, you sit down after feeling like you are gently surrounded by a sea, close your eyes and listen intently, not far away, there is the sound of waves splashing water. Hearing this sound, you squint your eyes and look towards the source of the sound of water. You found the answer – it was an aquarium, where fish swam quietly at night, and the aquarium lights were on, glowing with an eerie blue light. But you suddenly feel worried, if the light is always on, then these fish can get enough rest? Will not be like yourself, into another exhausted sleepy? The above scenario may be encountered by every fish keeper. Many friends who keep ornamental fish at home, in order to usually facilitate the fish or fish to fill the light will be installed around the tank lights, in general this light is on during the day, at least when someone at home is on, so when the family has orna

Fish Keeping Safe Stocking Guidelines

Image
For aquarists, the choice of the tank is crucial. A 10 gallon tank is considered a small tank, but for those beginners, it may be one of the most ideal fish tanks. First of all, you may have doubts about the 10 gallon tank, in your mind, you may not have formed a specific idea about the size. By industry standards, it's considered a small (mostly beginner) measuring anywhere between 20" x 10" x 12" and 20.25" x 10.5" x 12.5". Secondly, if you buy a ten gallon tank and add fish to it, there's a fact in front of you: you need to find out how many fish you can actually keep in it. In the case of freshwater and saltwater fish, how many can be kept? Maybe, you will find a suitable answer here. Safe stocking guidelines for aquariums There are several different types of aquarium fish. These species differ greatly in size and dietary requirements. Using the one-inch per gallon rule is simply not appropriate in many cases. The overstocking can result in sev

How To Adjust PH In Fish Tank

Image
As the saying goes, raising fish first raises the water. The quality of the water determines whether the ornamental fish in the aquarium can be healthy or not. Generally, the PH value that fish can adapt to is roughly 6-9, but different fish can adapt to different PH values. If you are not keeping ornamental fish that like acidic water or alkaline water like the colorful fairy fish or cichlid fish, then the PH value in the water is often easy to be ignored. In the process of fish breeding, we will encounter various problems about PH, if not handled properly, it will have adverse effects on the fish, and in serious cases, it will lead to the death of the fish.  This article will briefly discuss the problems related to PH. What is PH? PH is a measure of acidity and alkalinity, specifically a number between 0 and 14. PH equal to 7 means water is neutral, less than 7 means water is acidic, and more than 7 means water is alkaline. From a chemical point of view, PH is the specific expression
