How to Oxygenate a Fish Tank Without a Pump?

Here are the 12 best DIY methods to oxygenate your fish tank without a pump. Oxygenation of the fish tank is essential for the well-being and health of fish.

How to Oxygenate a Fish Tank Without a Pump? You can oxygenate a fish tank without a pump by using filters, extract oxygen from the air, bars, and sprays, plantation, add more organisms/ fish, wider tanks, water change, hard water, and by placing a fountain of water.

How to Oxygenate a Fish Tank Without a Pump?

Maintaining the minimum level of oxygen is a must for a fish tank. We often add a pump for the oxygenation of the aquarium. However, many people do not add this and use simple methods to add oxygen to the tank.

Use filters

A filter plays a vital role in generating oxygen inside an aquarium without using a battery pump. The internal portion converts the built-in energy into a source of oxygen supply. The filter of the water tank must contain electric power, and you must keep it clean.

The powerful filters help in the maximum transformation of water into the oxygen of the tank. The pressure of the water helps in the generation of the substance inside the tank.

The filters and their energy determine the building strength, and the low-quality filters cannot perform this activity. Clean filters have much more capacity to perform this task.

The flowing of water increases due to cleanliness, and is no restriction in the flow. The water produces waves, and it circulates all around the tank without crossing the sides of the aquarium.

As a result, it takes some oxygen from the surrounding environment, and diffusion occurs inside a specific place. The process increases the oxygen inside, and it enhances the oxygenation in every passing cycle. 

Extract oxygen from air with a cup

A small cup or a pitcher that you put inside the water tank helps in oxygenation in the best possible way. Take a cup of standard size that most people use for their aquariums. Fill the cup with the water of the aquarium; it should not contain fresh water in it.

Lift it to a certain height and then bend it towards the direction of the tank. Pour the water back inside the water tank. The process involves the transformation of the surrounding air to the oxygen in a tank. 

In the procedure, the cup does not only takes oxygen from the air. It also mixes it with the water of the aquarium. The height of the cup is the determining factor in the whole procedure. The higher the pitcher, the more is the level of oxygen.

Repeat the process and get more oxygen for the fish. Stable the cup and the tank, but the stability of the Picher is much essential. Human error should not disrupt the path of production. 

Use bars and sprays to produce oxygen in a fish tank

The bars for producing oxygen and the sprays are considerable in terms of oxygen in the fish tank. There is the complete involvement of the height. The water bar and falls have a certain length from the tank.

The sprays also pour water from a distance from the fish house, and hence they get oxygen from the air. The capturing power is remarkable for these things. They select mixing, where the spray mixes all the oxygen of the surrounding with the water inside the big pitcher.

There is a propelling force in these procedures. The pressure force is beneficial for the enhancement of oxygen level. The tank becomes extremely oxygenated, and there is no sense of deprivation inside the fish. They keep alive for a period with an excellent health condition. 

Add plants in the aquarium

It is one of the best and simplest methods to induce oxygen inside the water of your fish tank. The addition of more plants in the tank increases the level of a particular substance. It makes the environment fresh. You can plant lucky bamboo in the aquarium.

Plants have this capacity to inhale the carbon dioxide from the surrounding. They give back oxygen as a by-product. The process keeps on going multiple times in one single day. The maximum number of plants means the level of oxygen enhances to a limit.

The flow of water does not affect the process because they cover the complete bottom area. The procedure gets slow in the absence of light. At night continue the process by turn on the artificial light inside the tank. Change plants of the tank after every two weeks, or it starts working in a reversible direction. 

Add more organisms

In the case of oxygenation of the fish home, adding more fish to the tank is one of the best techniques. The swimming process of the fish increases the mixing of water. The more fish in the tank means more swimming, and hence water mixing enhances more than 10 times.

The movements of the fish during swimming contain the water which has more oxygen than the ordinary one. The water moves from bottom to top and left to right, and the level of oxygen increase amazingly.

They breathe well, and the respiration process becomes extraordinary. It is beneficial for the life and health of these mall creatures. You can create a blackwater aquarium at home.

Use Wider fish tanks

It is another way of improving and adding more oxygen inside the fish tank. Use the right glass cubical, and it helps in the enhancement of the material. The ideal tank provides maximum flowing of water, and fish moves with maximum effort and swimming positions.

The concentration of oxygen remains at a higher level at the top side areas of the fish house. The easy movement of the tiny thing inside the cubical allows the movement of oxygen all over the space. 

The water touches the air in a particular way, and oxygenation leads to a high level. The narrow tanks need pumps, and the wider ones allow the oxygen without an artificial force.

The wider ones have more interacting space with the air, and there is maximum diffusion of oxygen in the water. These are the factors for the healthy life and survival span of the fish. This is a must if you are hiding a fish tank from the landlord.

Change the water

The changing of water is the usual thing for fish. On a big scale, it has a specific impact. Change the old water with the new water, and it increases the level of oxygen amazingly. Always use fresh and clean water and do not empty the tank instantly.

The new water has more levels of oxygen as compared to the old water of the tank. It enhances the air and keeps the fish healthy. They live a long life depending on the fresh oxygen.

Do not just pour the freshwater, and always take precautionary measures. Shifting the fish in some other pitcher for a few minutes is a better idea. 

Hard water

Hard water in this process means water in ice conditions, and using ice cubes increases the level of oxygen. The high temperature inside the cubical decreases the oxygen, and in such cases, add few ice cubes and cool down the water.

Do not add ice cubes directly to the tank. They harm the tiny creatures in their personal space. Fill them in strong leather or any other ice bag.

Place the bag carefully at the bottom of the tank. Hold the bag in the aquarium if you find it comfortable. Once the water cools down, and then the level of oxygen gets moderate. 

Add a water fountain

Water fountains enhance the oxygenation because they pour water with an interaction. The air from the surrounding gets inside the droplets of water of the fountain.

The water fountain drops down in the tank and mixes its water inside the tank. Eventually, the level of the specific substance increases. 

Reasons for decreased oxygen in a fish tank

Temperature: Elevated temperatures inside the particular zone of fish causes the reduction of oxygen level. The hot water does not contain that much capacity to hold the oxygen molecules than the cold water. 

Excess amount of fish: Some people overstock their fish houses for the production of specific material. In some situations, it is the cause of hazard, and the small aquariums cannot digest a lot of fish, and they start feeling suffocated. It leads to a decreasing level of breathing, and some fish die due to this problem. 

Less light: The live plants produce oxygen in the presence of light, and it is their usual process. When there is no light, the process becomes slow, and then it gets dead. Never add the live plants in the tank, and add maximum lightning to keep them alive and leading the oxygenation. The algae in the tank produce a lot of breathing air, but it requires light. 

No movement of water: The movement of water accelerates the mixing of external air with the internal environment. The lack of swim movements causes deoxygenating and suffocation in the fish houses. 

Chemicals: People use chlorine and other chemicals to keep their aquariums clean. They cause a decrease in oxygen supply and level inside the fish life cycle. 

Is decreased oxygen levels in an aquarium harmful to fish?

The gasping shows the decrease level of oxygen inside the fish tank when they come at the top.

The lesser the swim movement of the fish means, it is lazy due to an inappropriate amount of breathing gas, you may notice that your fish is doing a headstand.

The abnormal eating habits inside the aquariums show decrease levels.

Rapid and inappropriate movements of gills show that the fish is not breathing normally. The oxygenation of the tank is a must in such situations. 

How much oxygen is required in a fish tank?

There is no specific limit of oxygen for any fish in the tank. The standard rule says that five-part per million is a good source for them.

They feel suffocation at low levels and especially when it leads to two-part per million. Excess oxygen is also not good for their health.

Always keep it at a moderate level. High levels cause the generation of bubbles that originates various syndromes in them.
