Air pumps work by displacing the water. Air pulled through the pump creates bubbles when released into the water. Bubbles displace the water, stirring it and sending the carbon dioxide to the surface. External pumps move the air via a hose attached to the pump that is dropped into the water.

The Basic function of an Aquarium Air Pump is to force air, through mechanical means, from the atmosphere into your aquarium. By forcing air into the water, you create water motion with the rising air bubbles, and also provide oxygen to the water that your aquarium fish and animals need to “breathe”.

Guidance:

There is no hard and fast rule for choosing an air pump. Some air pumps are rated for different sizes of tanks, but these ratings are, actually, nearly irrelevant to choosing the correct air pump.

If you are using the air pump only to operate an under gravel filter, and your tank is a standard size, then the tank size ratings on an air pump are probably relevant. However, if you are doing anything else with the air pump, or if your tank is not a standard size, then the tank size ratings for an air pump are highly irrelevant.

Here are some guidelines to have in mind when you are choosing an air pump for your aquarium:

• The more things you are running from your air pump, the larger air pump you will need, and conversely, the fewer things you are running from your air pump, the smaller air pump you will need.
• If you tank is more than 18-20″ (46-51cm) tall, you will need to get a special deep water air pump designed to push air that far below the water surface.
• The more resistance the things you are pushing air through have to the air, the larger an air pump you will need. (Larger air stones will provide more resistance than smaller air stones, and any air stone will provide more resistance than no air stone. Also, some kinds of air stones will provide even more resistance than others of the same size.)

When choosing an air pump, pick one a little larger than you initially think you will need. This larger air pump will help you by compensating for underestimating when choosing the air pump or by providing a little room for expansion if you decide you want that later.
