Is An Air Pump Necessary For a Fish Tank

An aquarium air pump is a special machine designed to use mechanical means to pump/ force air from the surrounding environment or atmosphere into your fish tank.

By pumping air into your fish tank, an aquarium air pump will create movement in the water which is nice and healthy for your fish. The air pumped into your fish tank will also aerate your fish tank water and, therefore, provide oxygen for your fish.

What are the advantages of having an aquarium pump in your fish tank?

Many beginning aquarists do not believe that it is necessary to have an aquarium pump. However, it is very necessary. Below are some of the reasons for or advantages of having an aquarium pump in your fish tank.

1. It will increase oxygen for your fish 

An aquarium air pump will continuously introduce air (and oxygen) from the atmosphere into your fish tank and release it in the form of bubbles. As the released bubbles travel through your fish tank, they will oxygenate the water and release CO2. This will make your aquarium water very healthy for your fish, live plants, and beneficial bacteria. 

2. It will improve water circulation 

As mentioned above, an aquarium air pump will continuously introduce air into your fish tank and release it in the form of bubbles. As the bubbles travel upwards through your fish tank they will create water motion or movement. This movement created will improve water circulation in your aquarium which is very important.

3. It will make your tank more attractive 

An aquarium air pump will pump air into your aquarium and release it in the form of bubbles as mentioned above. Having tiny bubbles flow upwards through your aquarium will make it look more attractive especially if you have decorated it well with live plants, small rocks, and so forth. 

4. It will make your sponge filter work 

If you have a sponge filter in your fish tank for solid waste removal, you need to buy an air pump to move the water and make the filter work since the filter does not come with a pump of its own like some other filters. 

As you can see from the above advantages, installing an aquarium air pump can be really beneficial.

What are the disadvantages?

There is only one disadvantage to owning an aquarium air pump:

1. It will increase your electricity bill

However, the increase in your electricity bill will be small since most aquarium air pumps run on very low wattage (about 4 watts). 

So there is really no big reason why you should not buy and install an aquarium air pump.
