The present invention provides a filter assembly for use in filtering and treating contaminated water 14 in an aquarium tank 40. A filter bag 10 is used for receiving a continuous supply of contaminated water 14 under a predetermined pressure. The walls 12 of the filter bag 10 are made at least partially of a porous filter membrane formed of a matrix of pressure displaceable fibrous material. As the filter 10 clogs with contaminants, bacterial growth and accompanying by-products, the fibrous material is displaced to increase the size of the interstices of the matrix to permit water 14 to continue to flow through the interstices and continue filtering. |
