Link Details  | ID: | 333 | | Title: | DIY Filter-In-A-Conch-Shell - http://www.petfish.net/kb/entry/13/355 | | Description: | A sponge filter works by having water come through the sponge and into its "lift tube." As it comes through the sponge, the bacteria living in the sponge help do useful things like remove ammonia. Once in the lift tube, the only way for the water to get out is through the top (given that the top of the tube is OUT of the water just a little bit). This is where the air pump comes in. The air displaces the water, forcing it out of the tube, where it trickles back into the tank, now clean. This provides for so low a current as to be practically undetectable. What I am adding to the theory is chemical filtration through the use of a carbon insert. Powered filters run water through a sponge to trap large debris, sometimes another for biological filtering (bacteria) and a carbon insert for chemical filtration. We simply add the carbon to the sponge filter so the water is forced to go through it before leaving the filter. It has worked in my tanks. | | Category: | Filtration | | Link Owner: | KingVinnie | | Date Added: | May 27, 2008 09:59:27 AM | | Number Hits: | 154 | | |
