Why do you need an air pump?

Facilitate water aeration

The air pump does help a lot in circulating the water. It thus reduces the need for frequent cleaning. This benefit is especially significant considering the fact that there is a trend in installing the big fish tank, and that the cleaning task can be very time-consuming and cumbersome.

Give some airstones

Some people like to have small bubbles or a mist of air flowing inside their aquarium. And an air pump can thus be a great ornament for the fish tank. Also, the tiny bubbles help to move the water through the filter more effectively, again facilitating the cleaning task.

Promote oxygen circulation

The truth is, it is not compulsory to have an air pump inside the fish tank to ensure enough oxygen for the creatures. However, a quality air pump helps with the release of carbon dioxide from water and the oxygen intake from the air for the fishes. And with the addition of oxygen, it prevents the water to become stagnant.

Match with filters

The filter is mandatory for any aquarium setup, and there are some filters that require an air pump to operate. In such cases, having an air pump even becomes a prerequisite for filter installment. Otherwise, the water soon becomes dirty, ruining the habitat of the creatures inside the fish tank.

Work with protein skimmers

Besides filters and airstones, protein skimmers in salted water tanks need air pumps to work properly. In other words, installing air pump contributes to providing a healthy environment for the fishes and the plants in the tank. Also, the air pump can spin wheels, turn valves, lift the object and work with many accessories inside the aquarium.

How does it work?

Commonly, the air pump is attached outside of the fish tank, with the tube stay inside it. When it works we see the tube diffusing the air and create the tiny bubbles through the airstone.

A standard air pump uses an electromagnet to vibrate the rubber diaphragm, which then generates the air flow. It also indirectly increases the amount of oxygen in the tank water. The small bubbles from the airstone do not integrate with the tank water. Instead, they agitate the surface area inside it.

And when the bubbles break at the surface, they release carbon dioxide. Thus, more oxygen can take their place when they come into contact with the water molecules. As the surface area of water becomes bigger, it will absorb more oxygen.

Finally, the air pump promotes water circulation by releasing the air to the bottom of the fish tank. As it pushes deeper water to the surface, this movement allows the highly oxygenated surface to travel towards the bottom.

What to consider when buying an air pump?

Tank size

As a rule of thumb, the bigger the tank is, the stronger the air pump should be. Also, you can install more than one air pump to ensure the even distribution of water and oxygen aeration.

It’s ideal to check the tank size ratings for the air pump to ensure the perfect match. And when choosing an air pump that fits, look at its volume per hour. By ensuring the pump can handle more than enough amount of water, you will avoid any issue when running the accessories.

Also relating to the tank size, investigating its headspace will help to determine what air pump should be in use. Specifically, the head space is the height of water needs to be pumped against the gravity force. Again, the deeper the water needs to travel, the stronger the air pump should be.

Objects and resistance

The more things inside the fish tank need an air pump to operate, the larger and stronger an air pump you should install. Thus, it’s important to take into account all the accessories inside the tank before choosing an appropriate air pump.

Besides considering the quantity of the objects, it’s also crucial to take a look at their quality. The more resistance they push the air through, the larger an air pump you will probably need.

Personal needs

The best air pumps do not need to be the strongest ones. Instead, a good choice of an air pump should be one that fits your own requirement. For example, if you just need an air pump to run an under gravel filter, then the air pump should not be too strong. Otherwise, it will blow the floor gravel.

Also, if the tank does not follow the standard size, then the power of the air pump should fit accordingly. It’s best to consult the reviews to ensure that particular air pump is a good choice. Find those owning the same size tank and look for their consultancy.
