5 Best Tips: How To Lower Ammonia In Fish Tank?

How To Lower Ammonia In Fish Tank? There are many possible causes of an increase in NH3, a harmful toxin in an aquarium. What are the causes and how to reduce the concentration of NH3? All will be explained through the following article.

Why is the concentration of NH3 in the aquarium increased?

  • First, because the owner overfeed the fish, the excess food that accumulates for a long time will create ammonia poison gas (NH3).
  • Second, because the pH in the aquarium is too high, when the pH is above 8.5, it means that the water environment is strongly alkaline. When the pH increases, the amount of NH3 (gas) in the water increases. If you increase 1 pH unit, the amount of NH3 (gas) will increase 10 times. This environment forces the fish to be forced to metabolize more, so the fish can slow to develop, causing an increase in ammonia – the foundation of the ammonia compound (NH3).
  • Third, because the microbiological filtration system is ineffective, unable to filter feces, uneaten food, dirt … in the lake.

How do I know if the concentration of NH3 increases in the aquarium?

Purchase an ammonia concentration test kit

You can buy this kit at most pet stores. This kit will help check the full concentration of ammonia in the aquarium.

Measure the pH of the water

The pH of the tank can directly affect the ammonia concentration in the water. By measuring the pH regularly, you can ensure ammonia concentrations are not at toxic levels.

Note: Need to check the water at the right time. The best time to test the water is right before feeding the fish when the new food has not been decomposed. Ammonia concentration will reach its highest level about 90 minutes after you feed the fish

Harmful when the concentration of NH3 increases in the aquarium

High NH3 reduces immune function and resistance, prevents metabolism, oxygen, inhibits nerves, so fish is susceptible to other diseases such as: curvature in koi fish, tumors …

NH3 is very toxic because when present in high concentrations, it will burn the gill tissue of the fish, burn the skin and intestinal tract of the fish. In cases where ammonia levels are present in the water, not purged in time, the fish will grow slowly, the fish will lose color, and the immune system weakens and becomes susceptible to infection. If the condition does not improve for a short time, the fish will die from acute NH3 poisoning.

How To Lower Ammonia In Fish Tank?

Eliminate excess melon in the aquarium

Rotten organic matter is an important factor causing the ammonia concentration in the tank to rise. You can use a fish racket to take out all the excess (basically everything except the fish and live plants you want to keep) to reduce and prevent ammonia levels in the tank. tank increased.

  • Uneaten food contributes significantly to increasing ammonia concentration in the tank.
  • The decomposition of fish waste also increases ammonia concentrations.
  • Dead plants or dead fish in the tank will release a sizable amount of ammonia.
  • Take care to clean the water filter to avoid the accumulation of organic material being pushed back. However, you should not change the filter pad to avoid imbalance of bacteria in the water.

Change the aquarium water

Partial water changes in your tank are a great and effective way to reduce ammonia levels while keeping the tank clean at the same time. You should change some of the water in the tank about once a week or more often depending on the condition of the tank. To check, you can use a fish racket to evenly the substrate in the tank, if there is a lot of dirt emerging then you need to change the water more often.

  • Leave the clean water out overnight to reduce the chlorine in the water, or you can treat the water with chlorinated agents.
  • Wash your hands well to remove all residues of soap, lotion and other potentially contaminated substances, and then dry them with a clean paper towel.
  • Disconnect all electrical equipment near the aquarium to prevent the risk of electric shock. You should only plug in after the water change is done and make sure everything is dry.
  • To ensure the quality of the tank, you should change about 30% of the water in the tank. For example, for a tank with a capacity of 38 L, you would need to change 11.5 L of water.
  • You don’t have to move your fish to another tank when you change a part of the water, just be careful not to startle the fish when you put your hands in the tank.
  • Shave off the algae growing on the wall of the tank. You can buy a professional algae scraper or simply use an old bank card to do this.

How To Lower Ammonia In Fish Tank

Use a suction hose to put about 30% of the water in the tank into a bucket or other nearby tank, then slowly fill the tank with clean, dechlorinated water.

Reduce the amount of food eaten by the fish

If the fish does not finish the food, the amount of food remaining in the tank may be the cause of the increase in ammonia levels. You can minimize this risk by limiting the amount of leftovers you fish.

Note that changing fish feeding habits will not reduce the high ammonia concentration in the water; however, this will help prevent ammonia levels from rising after you’ve changed the water in the tank.

Put probiotics into the water

Probiotics often gather at the bottom of the aquarium and help convert ammonia into relatively harmless nitrogen components. If the tank is new or the amount of probiotics in the tank has been significantly reduced, what fish experts call “new aquarium syndrome”.

Some aquarists put probiotics into their tanks by placing an inexpensive fish or two into the tank to take advantage of the probiotics from their waste. If you want to do this, you can place your goldfish in a cold water tank, a barb in a warm water tank, or a sea bass in a saltwater tank.

You can also introduce probiotics into your tank by spreading some gravel from the old tank to the bottom of the new tank.

Reduce the pH of the tank

Using a pH regulator (purchased from a pet store) is probably the easiest way to lower the pH of your tank.

Use mud moss: Mud moss can be purchased at home appliance stores, you can wash it first to clean and remove the color of mud moss then put them in a cloth bag and put in a bag. filter box, this method is quite safe because the mud moss helps to reduce the pH very slowly to avoid shocking our fish.

Use almond leaf: The almond leaf has a slightly natural acid content, so when you use the almond leaf to enter your aquarium, the pH will drop 1-2 degrees. Note that use dry almond leaves and wash them well before adding them to the tank to avoid causing disease to the fish.
