<p><b>New page</b></p><div>'''UGF''' means Under Gravel Filter.<br />
<br />
This [[filter]] provides both mechanical and biological filtration. It is a perforated plate placed just off the bottom of the aquarium tank and then covered in gravel. In the corner of the plate is a tube which sucks up water. This causes the water to be pulled through the gravel, under the plate thus pulling detritus and water through the gravel and into the [[nitrifying bacteria]].<br />
<br />
The drawback to this filter is that it can not be dismantled without breaking down the entire tank. It can clog and it is not a good base on which to grow plants as the substrate needs to be quite thin.<br />
<br />
<br />
This type of filter was once very popular. But now is being slowly dropped in favour for the less troublesome internal or external [[box filter]].<br />
