Reduce ammonia in fish tank heres how to fix itDoes your search history include the term, ‘reduce ammonia in fish tank?’ If yes, it’s likely you’re frantically searching for solutions to the inhabitants of your aquarium. Ammonia is a natural component of your tank’s ecosystem.

The compound results from various sources, such as fish waste and decomposing food particles. That’s where our ammonia-busting fish tank guide can be of help. Keep reading as we’ve compiled several practical ways to lower ammonia levels in fish tank(s) so that your fish continue to thrive.

What Causes High Ammonia Levels in Fish Tanks?

We’ve focused on the methods aquarists can adopt to control or reduce ammonia in fish tanks. However, as a fish keeper, you’ll be better prepared to handle the situation if you’re aware of possible ammonia triggers. That’s what we’ll be highlighting in this section.

Furthermore, this process is known as “Break in Cycle” since it lacks the good bacteria that should be present in the tank. The reason why these bacteria are good in the water is because they prompt safety in the water level regarding both ammonia and nitrogen.

Additionally, they prevent the excess of nitrogen and ammonia in the water, so that the water in the tank where the fish swim doesn’t turn toxic.

– Waste Buildup

Remember when we said the breakdown of organic substances can eventually lead to higher ammonia levels. However, what are the said organic substances exactly? Things like plant debris, rotting fish food, and even dead fish contribute to ammonia formation.

Removing the source(s) of ammonia can help you improve water quality. For example, fishing out rotting plant leaves and vacuuming the gravel for bits of rotten food can all help cut back ammonia production.

– Inadequate Filtration

Another possible cause for ammonia in fish tanks is an inadequate filtration system. More often, first-time aquarists can make the mistake of buying a filter that doesn’t correspond with tank size and water capacity.

In simple terms, the filter isn’t powerful enough to keep up with the cleaning requirements of the aquarium. Furthermore, a malfunctioning filter can have the same effect.

Be sure to check your filter whenever you notice ammonia levels rising in your tank. Often the first sign of a filter problem is an ammonia spike.

A protip to be prepared for such situations is to have a backup cycled filter at the ready. This allows you to seamlessly switch the filters in the problematic tank without worrying about a drop in beneficial bacteria.

– Overstocking

Did you notice how every fish care guide comes with a tank size requirement? There’s a reason for that. You can only stock so many fish per aquarium according to its size and capacity. If you exceed that limit, you’re potentially tempting fate.

Increasing the number of fish in an aquarium also means an increase in fish waste production, invariably leading to an ammonia spike. Be mindful of how many fish your tank can safely accommodate to avoid such concerns.

If you still have a mind to add to your local fish population, it’s best to set up a new aquarium to make sure there’s enough room for everyone without the worry of rising ammonia.

How To Reduce Ammonia in Fish Tank?

One of the most common reasons why ammonia levels spike in established fish tanks is inadequate cleaning. Ammonia is naturally occurring in aquariums because it’s a product of biological breakdown. Things like rotting food, plant debris, fish waste all contribute to the presence of the compound.

Plus, an aquarium is a closed-water system as there’s no source of continual fresh water to dilute the substance. Thankfully, fish keepers can take certain measures to ensure their fish tanks have minimal ammonia levels and keep the habitat safe for tank inhabitants. Here’s what a few of them are:

– Filtration

As we stated earlier, fish tanks need a helping hand when it comes to controlling toxic substances like ammonia. A top-quality filtration system (that’s powerful enough according to your aquarium size) can go a long way in keeping nitrites under control.

Filters for fish tanks contain several types of filtration media (mechanical, biological, and chemical) to help keep the water as clean as possible. They also help give the beneficial bacteria room to grow, which aids the nitrogen cycle and helps cut back nitrites.

In short, there’s no avoiding using a filter in the aquarium hobby. However, if you’re new to fish keeping and haven’t equipped your tank with a filter, you need to get one installed as soon as possible.

A water filter that corresponds to your fish tank capacity will simultaneously work to keep the water cleaner for longer while adding to the numbers of beneficial bacteria that help break down nitrites into nitrates (which isn’t as harmful to fish as the alternative).

If you already have a filter installed and are still facing rising ammonia levels, your filter may not be powerful enough, or it may require cleaning. Note that you should be careful when cleaning your filter because regular water can destroy the beneficial bacteria living in the filter’s biological media. To avoid such concerns, use aquarium water to cleanse your filter.

– Nitrogen Cycle

The nitrogen cycle is responsible for converting harmful ammonia into nitrite and then nitrate that plants can utilize as a nutrient. Various types of beneficial bacteria support this endless cycle of compound transformation. These are vital to sustaining livable conditions for fishes in aquariums.

The chances of ammonia spike in newly set-up fish tanks are much higher because these don’t have an established cycle. That’s why experts recommend setting up your fish tank with hardy species that can withstand higher-than-usual ammonia levels.

You can kick-start the nitrogen cycle in your fish tank by adding a few fish (thereby providing a source of ammonia that the beneficial bacteria can feed on). However, always have a water testing kit handy and be highly vigilant about monitoring ammonia levels for the first four to six weeks after setting up the tank.

– Water Changes

One of the easiest and quickest ways of lowering ammonia levels in fish tank settings is to conduct a water change. A water change is designed to introduce freshwater into the aquarium to dilute the presence of problematic compounds, including ammonia.

Generally, it’s better to opt for smaller and more frequent water changes than conducting 30 to 50 percent changes, increasing the chances of fish experiencing stress. Performing significant water changes can negatively affect beneficial bacteria numbers, which you should always avoid.

A good rule of thumb to follow for water changes is 10 15 percent per week. If you’re the proud owner of a community tank with a sizable number of fishes, you can opt for a 25 percent weekly water change.

– Tank Size

You can reduce ammonia levels in fish tank arrangements by bumping up the tank capacity. This is especially true for fish parents with a growing community tank.

The logic behind this premise is simple. Increasing the water capacity of your aquarium will slow down the time it takes for ammonia to build up in the water. Nevertheless, tackling ammonia this way may not be a viable solution for all. At times aquarists are dealing with space constraints and have no way of accommodating a larger fish tank. But, even so, you still have alternatives.

For example, instead of buying a bigger tank, you can set up another similar-sized tank to divide the number of fish among them equally. This isn’t an ideal resolution since it may increase your workload in terms of tank maintenance.

Additionally, controlling the water parameters of larger tanks is more straightforward than regulating smaller setups where fluctuations occur more frequently.

– Aquatic Plants

Another trouble-free and beneficial way to get rid of ammonia in fish tank(s) is to add aquatic plants. Aquatic plants use nitrates in the water as nutrients, improving water conditions. Besides that, live plants also produce oxygen and reduce carbon dioxide in the water to provide a healthy environment for your fish.

If you’re concerned about the extra work you’d have to put in looking after live plants, you can always opt for easy to care for species, such as Amazon Sword, Anubias, Java Fern, etc. Starter plants barely require any upkeep and provide various advantages like ammonia reduction.

– Aeration

Lack of aeration can cause dissolved gases like ammonia to stay in the water for longer, leading to high ammonia in fish tank settings. On the other hand, increased aeration can lead to a faster rate of ammonia diffusion, leading to reduced ammonia levels in the water.

Setting up a filter system in your aquarium can provide some form of aeration. However, if the tank’s size capacity is significant or your fish tank is overcrowded, it calls for extended aeration needs. You can help increase aeration levels in your fish tank by adding an air pump or aeration decorations.

– Neutralizing Drops

Neutralizing drops are an impermanent way to reduce ammonia levels in fish tank environments. They’re a type of aquarium treatment that makes the effects of ammonia harmless.

However, be advised that neutralizing drops don’t remove ammonia from the water. This means you’ll still have to rely on biological filtration to clear the aquarium water of the chemical compound.

– Hygiene

At the risk of sounding like a broken record, the breakdown of organic substances (fish food, fish waste, plant detritus) leads to the formation of ammonia. Hence, if we stick to the laws of science and remove the potential ammonia-building sources from the fish tank, it’ll automatically lead to lower ammonia levels.

That’s one huge reason why experts recommend regular tank maintenance. From vacuuming the gravel and sucking up bits of rotting fish food to cleaning the filter (do this with extreme care), hygiene upkeep can help cut back ammonia production.

– pH Levels

If you’re familiar with the mechanics of how a nitrogen cycle functions, you’ll know that ammonia is only created when the pH level of the water goes above 7.0 (neutral). Before that happens, the original compound that organic substances release as ammonium, which is much less toxic to fish.

That means controlling the pH level of water is also a handy way to reduce ammonia levels in fish tank(s). You can do this easily by purchasing a reputable chemical pH adjuster.

Moreover, it is important to be advised that the pH range of a fish tank depends on its fish inhabitants. Fish keepers can’t change pH levels too drastically because doing so can affect the health of your fish. Not to mention, adjusting pH levels isn’t a permanent solution to the ammonia problem.

Frequently Asked Questions

Furthermore, there are other questions regarding your worry about ammonia in the tank which has reached an excess level, that is why we present to you additional questions along with their answer to help you clarify the problem, and give you a better insight on the solution along with commonly asked questions.

1. How Do You Neutralize Ammonia in Water?

The best and most-time consuming way to ensure the ammonia levels in your tank convert to the more harmless nitrate version is a functioning nitrogen cycle. That is why, it is best to advise water change frequently. Other methods of ammonia reduction include adding live plants, increasing aeration, using neutralizing drops, and chemical pH adjusters. But these methods aren’t long-term solutions.

Maintaining tank hygiene is also an excellent way to counteract ammonia formation because it helps remove substances that contribute to ammonia formation.

2. Do Water Filters Remove Ammonia?

Having in mind that ammonia is water-soluble, it is challenging to remove the level of ammonia with a simple filter. However, reverse osmosis or even ion exchange can occur with filtration, hence this will hinder the distillation of ammonia in the tank through the filter.

Note that the nitrogen cycle helps create beneficial bacteria that aid in the breakdown of ammonia to nitrates, which filters can remove.

Furthermore, removing the the nitrogen will balance the pH of the water.

3. How High Will Ammonia Get During Cycling?

The concentration of ammonia should start from 2.0 pp and not exceed 5.0 pp. If it exceeds ammonia is reached, then the ammonia level will intoxicate the water parameters, which will not only impact the life of the fish in the tank, but also it will intoxicate the plant life as well.

4. How Long Does it Take for Ammonia To Spike in an Aquarium?

It usually takes about two to six weeks that ammonia would spike in an aquarium, as long as the temperature is kept below 70 F. The reason why the spiking process takes a long time is because the bacteria that are responsible to nitrify the water need some time to grow, hence they grow slowly.

5. How Long Does it Take Fish to Recover from Ammonia?

Reduce ammonia in fish tankIt would take your fish around five to six days to recover from the abundance of ammonia in the tank after you have reduced it. Nonetheless, it is best to keep this treatment going and not stop after you see that your fish are doing better, because they still some time to develop to the normal level of the water since they were in a high level of ammonia in the first place.

Wrap up

Being able to control ammonia levels might seem like sorcery to new fish keepers, but the truth is it’s a matter of simple logic. All you need to do is take note of ammonia triggers and do what you can to avoid them. Here’s what you need to keep in mind regarding the reduction of ammonia and its spiking:

  • One of the most common reasons why ammonia levels spike in established fish tanks is inadequate cleaning.
  • Unfortunately, other causes can lead to ammonia spikes. These include overstocking (too many fish in a single tank), inadequate filtration, or unchecked waste buildup.
  • Aquarists looking to reduce ammonia levels in aquariums can rely on several practical solutions, some of which aren’t permanent.
  • Another long-lasting solution to reducing ammonia is a robust filtration system backed up with biofilters. These help keep the tank water clean and provide ideal settings for beneficial bacteria colonies to thrive.
  • Conducting regular water changes can help dilute the ammonia in the water column and replenish the essential elements. It’s a smart way to give your tank’s ecosystem a chance to catch up.

Keeping a check on the causes of ammonia is much easier than reducing rising levels. So, staying ahead of the ammonia curve is the smartest move.
