Thinking of buying a aquarium air pump? Here’s the top 6 frequently asked questions about aquarium air pumps.  

Why do I want an aquarium air pump?
Your fishes really need to breathe, and aquarium air pumps provide the required oxygen. The oxygen dissolves in the water, and when the water goes through a fish’s gills, the dissolved oxygen can be consumed and the fish breathes. With no pump, your fish may suffocate.

How powerful does the aquarium air pump need to be?
It usually depends upon not one but two things: how spacious your tank is, and how big your fishes are. Usually, the more spacious your aquarium is, and the bigger your fishes are, the stronger your tank air pump should be.

May I use an aquarium air pump for more than one tank?
Yes. If you purchase air hose adapters(that normally come in packages or with air stones) , feel free to use the adapters for you to split the air line and direct the air to a number of fish tanks. Take into account, however, the more divided the air line is, plus the more aquariums your pump is giving air to, the more powerful your aquarium air pump has to be.

Would I need accessories for my aquarium air pump?
You will most probably have to order additional air hosing and air stones, together with necessary adapters, because many aquarium air pumps usually do not supply such products in the package.

Are aquarium air pumps noisy?
The area will depend on the item. In case noise and vibration is an issue to you, try to order an aquarium air pump which has additional insulation or rubber feet. Remember to place the pump over a flat, solid surface, away from other stuff.
