7 Best Aquarium Air Pumps to Maintain Good Air Supply

Aquarium air pumps are an important accessory for all kinds of tanks. They are needed not just for pumping in oxygen but also for water circulation. An aquarium pump is also what you need to run those cute aerating aquarium toys and decorations.

The basic purpose of a fish tank air pump is to pull oxygen from the atmosphere outside the tank and pump it through the water in the tank.

This oxygen is needed by fish and if you have very active fish in your tank they probably need more of it. Aquarium air pumps take care of this by creating air bubbles in the water.

Use of an air pump in a fish tank

For Aeration

Fish breathe underwater by taking in the oxygen that is dissolved in the water. While the water can always absorb oxygen from above its surface in the tank but that is not enough to meet the oxygen requirement of the fish. This is where the air pump for the fish tank steps in and provides the amount of oxygen sufficient for the fish.

A fish air pump facilitates surface agitation and gas exchange. When it releases bubbles in the water, the oxygen at the surface of the water makes its way in and the carbon-di-oxide in the water makes its way out.

For Filters

A lot of filters like the under gravel filter and sponge filters need an air pump for functioning. As these pumps power the water filters, they also help in developing bacteria colonies in the filter.

Sponge filters do not have a motor attached to them and they need an air pump for the sponge filter to function. You need a sponge filter in your tank because they help in the thriving of beneficial bacteria in the fish tank. The air thrust from the aquarium pump pushes air through the sponge filter to make it work.

For Quarantine Tanks

When you quarantine a sick fish in a separate tank, you have to raise the temperature of the water for the fish for it to fight the infection. It leads to oxygen loss in the water that can be avoided with an air pump in the quarantine aquarium.

Using an air pump for the aquarium will let you raise the temperature without losing any oxygen from the water.

For Bubble Maker Ornaments

Haven’t you spent time watching the bubble maker ornaments release tiny crystal clear bubbles into the water of your fish tank, as your fish wade through it? These air bubbles are not just entertainment for you but also your fish.

A lot of aquarium decorations need the fish tank pump to function. Treasure chests, divers, submarines, fake corals, and volcanoes add the fun element to a simple aquarium.

For Air Stones

Air pumps are also used for air stones in the fish tank. These air stones let out tiny bubbles when the air pump pushes oxygen through them.

For Protein Skimmers

Protein skimmers remove protein and organic water from the fish tank. They use an air stone powered by the air pump to do this.

We looked at some of the air pumps that are an excellent buy for your fish tank. With so many choices available, these aquarium air pump reviews will help you make an easy selection.

Things to consider before investing in an air pump for your aquarium

You can decide which one of these is the best aquarium air pump for your fish tank based on what is more important to you. Some of these are silent pumps while the others are battery-powered. Depending on your requirement pick one that also suits your budget.

Do not buy a cheap air pump since it will neither be durable nor will it serve the purpose of providing ample oxygen to the fish.

Some other things that you must keep in mind before buying an air pump fish tank are:

  • The aquarium pump you decide to buy depends on the number of accessories you plan to connect to the air pump. The more things you run, the larger pump you need. It is better to decide the number so that you can buy a pump accordingly.
  • The best aquarium pump is one that suffices the oxygen requirement, is within your budget, and can accommodate all your accessories like a fish tank bubbler.
  • If you have a deep fish tank, buy an air pump that is specially designed for them. The pump must be able to push air down the water surface
  • Buy a larger air pump so that you don’t need to replace one in case you plan to add one or two additional aquarium decorations or air stones.
