Beneath gravel filters consist of a plastic grate or "filter plate" which lies beneath the gravel of the tank.

This plate permits water to flow freely under the gravel.

Water is drawn through the gravel (which acts as a mechanical and biological filter).

To move the water, you can use either electrical power heads or air pumps. A electrical power head will pump water out of the leading of the lift tube and into the tank,

and air pump will blow bubbles at the bottom of the lift tubes and the bubbles will lift water up the lift tube and 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 by means of the gravel exactly where it is cleaned.

The gravel it self supplies mechanical filtration by catching huge free-floating particles.

The gravel, as nicely as the filter plate, tank bottom, and lift tubes, give a bed for the bacteria of a biological filter. Underneath gravel filters largely provide biological filtration.

Some beneath gravel filters come with carbon cartridges that fit the leading of the lift tubes.

These are needless and can be harmful. There is not sufficient carbon in these cartridges to supply sufficient chemical filtration,

if you are operating your filter with an air pump, you are not moving enough water through the carbon to provide very good chemical filtration,

and the carbon will restrict (and might even stop) water movement through the filter. In addition, when the carbon gets to be saturated,

it is attainable for it to get started to release other toxins into your tank. If you do choose to use carbon cartridges with your beneath gravel filter,

you must exchange them at least 3 times a month.

Remember to remove any carbon from the tank or filter before you medicate (if the carbon is functioning, it ought to get rid of the medication from the tank in beneath an hour,

in which case your fish won't get treated).

Also remember that water will follow the path of least resistance. If there is an region of the filter plate that is exposed (perhaps by digging fish),

or if you have a electrical power head on one side and an air stone on the other, you might not have any filtration from your beneath gravel filter.

Below gravel filters, when correctly maintained, supply effective biological filtration and sufficient mechanical filtration.

I would strongly recommend an underneath gravel filter for the first filter in a basic tank.

You will not have to tear up your tank to clean your filter with an beneath gravel filter, simply because to clean it,

all you have to do is siphon off the accumulated debris in the gravel when you do your normal water change.
