A popular misconception is that an air pump is crucial for an aquarium. It is often believed that it will bring more oxygen to your tank, but this is not actually true. What air pumps do is improve circulation and increase surface area.
And how does that help your aquarium? Improving the circulation will move water with more carbon dioxide up where it can take more oxygen. By increasing the surface area water has a better opportunity to release more dioxide and exchange it with oxygen.
The only necessary case when you really need an air pump is when you are using a filter which operates through an air pump. In this situation, obviously, the filter will not be able to work without it.
When choosing an air pump you need to think about a few things. The size of your tank is the most important. There are weaker models for small tanks, but if you have a significant one, you will need a pump for deep water. Also, if you are going to have things other than the filter that will run from the pump, you will need a stronger one. You can read more on how to choose the correct air pump for your aquarium below our list.
One of the most important features in an air pump for customers is usually how quiet it is. With this article, we aim to direct you to the best quiet air pumps on the market. All models on our list are also available on Amazon at the best market prices.

How to choose the perfect air pump?
As we already mentioned in the beginning, there are a few factors to look for when choosing the perfect air pump. Here they are:
This is an obvious one but we still cannot miss it. Larger tanks will require a bigger and more powerful air pump. Our small tip with this is to always choose a slightly bigger one than you would actually require, just in case.
How many objects will run from the pump?
You need to think about if your filter or anything else will be run by the air pump. The more things, the bigger the capacity you will need.
If your aquarium is very deep, you will need a deep-water air pump. We have included a few of this type in our list!
You need to think about the resistance that objects and decorations will provide to the air flow. If there is more resistance, you will need a larger air pump.
Despite not being a necessity, air pumps are very beneficial. They increase oxygen levels and improve water circulation. This also helps the gas exchange, it creates currents for the fish, and it improves filtration. Also, fish love playing with bubbles!
