Aquarium Pump: The Guts of Your Aquarium

By Jill Kaestner


A fish tank pump, or an aquarium pump is a requirement in your fish tank. Fish need oxygen to remain alive. Only a few kinds of fish can take in oxygen by coming to the surface of the water, and these are often the giant type that aren't typically to be found in a fish tank.

To oxygenate water for your fish, a fish tank pump is employed. It will bring in oxygen, and at the same time it'll filter the water in the tank so it's clean of carbon-dioxide waste.

The mechanism of a aquarium pump is basic. It draws in oxygen by moving the water surface in order that it's interacting with air. During that interaction, some of the air gets into the water and the oxygen inside this air is utilized. If there wasn't any movement of water in the tank, it would not draw in any air and so there would be no oxygen.

The fish will be inhaling oxygen and releasing CO2 which needs to leave the water. Similar motion, due to the fish tank pump will allow the CO2 molecules to get together, form bubbles and escape the tank. Without the motion, the fish would suffocate because the carbon-dioxide wouldn't form bubbles and move upwards. This is why a fish tank pump is claimed to help in purifying too.

Different Sorts of Fish Tank Pumps

1. External Aquarium Pump

This kind of pump draws air from the open air and pumps it into the fish tank thru a hose attached to the pump. Once the air is pumped in, it causes water movement and therefore the oxygenation, and carbon-dioxide is released too. It's usually more suitable for little fish tanks or aquariums. These pumps could be a bit pricey apropos maintenance though. They clog frequently and need terribly frequent cleaning.

2. Internal Aquarium Pump

This kind of pump is immersed in the water. It creates currents that move the water so that water surface can break and admit oxygen while at the same time letting out carbon dioxide. It's customarily found in bigger fish tanks that would need more than just bubbles to cause water movement. The external pump is fitted with a powerhead, which is the one which causes the currents. You need to be careful though, because some fish can be hurt by powerheads.

Ideally, you are going to mix different types of fish in your fish tank. A bigger one will have a larger range of fish and there is sure to be some little ones in there. A robust current would overmaster and tire them and they would ultimately die. A strong current also means that food is continually being swept away, and a slow fish may never be able to get a bite to eat.

Since it's a must to aerate your water in a gigantic tank just as in the small one, the move to make is know the categories of fish that can cope with the kind of current that the pump will provide. It is easy to get steering from the tank and pump sellers, or you can go for a tank that's already fitted with a pump. It'll save you all of the looking and fitting of the right pump for your tank.

There also are other things to think about. The scale of your tank is a factor as well as the sort of plants that'll be in it. The more the plants, the bigger a pump you will need.

A fish tank pump is an indispensable component of your fish tank "it's really its life line. You have to know precisely what pump is the best for your tank. Otherwise, go for a tank that comes fitted with a pump.
