This article, in addition to describing this indispensable accessory, meant to be a source of clarification about the real utility of 'aquarium aerator in the light of my own experience and from information obtained from various technical sources.

Contrary to what many believe, the aerator does not produce oxygen but is simply a pump that thanks to the rapid vibration of a rubber membrane, injects air (taken to its surroundings) at low pressure at 'inside of a rubber tube into the water to flow well.

In order to make distribution more efficient air output end, is placed a special "speaker" is commonly known as "porous" or "POROUS STONE", and its function is to break down the air that normally would exit in the form of large bubbles in many small bubbles, increasing the ability to move water to transport it to the surface.

The effect created is to create a continuous movement of water avoiding the stagnation in areas not reached by the flow of water from the filter, and generate a displacement of water to the surface where gas exchange takes place that produces more oxygen (and conversely a dispersion of carbon dioxide).

It 'important to stress that this type of air distribution, does not contribute directly to the oxygenation of water, because the very short time permanence of the bubbles in water that does not allow a optimal gas exchange. The real action of oxygen is due to upward movement of product in water in contact with air results in a greater absorption of oxygen .

There are ventilators of varying scope and especially of different qualities, the choice depends on the size of the tank where it will be used and the noise you want to achieve. Normally a higher cost products are more silent and reliable. Consumption are very low, hovering at an average of 2-8 watts.

use of air is indicated, especially in periods where the temperature is hot (summer) to compensate for the decrease in oxygenation, or to quickly disperse excess CO2 dangerous for fish, or any other emergency that requires an increase in gas exchange and increased water handling. It is not advisable to use constant and very prolonged in the case of planted tanks because the action of dispersion of CO2 would be detrimental to the life of the plants.

is often used for the operation of so-called "air filter". Pumping air into a tube immersed in water, the bubbles push the surface part of the water, creating a recirculation inside the tube (which can be loaded with filter media) that varies depending on the power of the air.
