AQUARIUM PUMP SELECTION
Using Aquarium Pumps
When setting up a home aquarium it is important to properly set up the aquarium pump. The lack or incorrect settings of an air pump would have an effect on the fish as it will not be able to breath and eventually die. Here are some important tips for anyone who is planning on installing an aquarium air pump in their fish tank.

The Need for Aquarium Pumps
Most aquariums need air pumps to function. In most cases, air is pumped through tubes into the water and through the filter. Air is mixed with the water to provide oxygen for fish in the aquarium. There are several types of aquarium pumps. The type of aquarium pump you should buy will depend on the type of aquarium you have and the number of fish in your tank.
One of the simplest and most common used aquarium air pumps is the ‘air stones’. These are ideal for smaller aquariums and tanks. The system works by having one end of the tube attached to a tiny orb which helps mix the air with the water, forming many tiny bubbles and spreading it throughout the tank.
Under Gravel Aquarium Air Pumps
Consisting of a plastic grate or “filter plate” the Under gravel filters lies under the gravel of the tank, this allows water to flow freely under the gravel. Acting as a mechanical and biological filter where water is drawn through the gravel. So you can use either power heads or air pumps to move the water. A power head will pump water out of the top of the lift tube and into the tank, and air pump will blow bubbles at the bottom of the lift tubes into the tank. As water is moved out of the lift tube, it is replaced with water from under the filter plate, which in turn pulls water through the gravel where it is cleaned.
The gravel itself provides mechanical filtration by catching large free-floating particles. The gravel, as well as the filter plate, tank bottom, and lift tubes, provide a bed for the bacteria of a biological filter. Under gravel filters primarily provide biological filtration.
