An apparatus is set forth permitting unitary replacement of the filtration components contained therewithin, wherein an elongate cylindrical housing includes a lowermost filtration polymeric fibrous member underlying a coaxially aligned replenishable mesh bag containing ammonia activated charcoal therewithin. Upper and lower end caps are replaceably mounted relative to a central coaxially aligned body to permit replacement of the components therewithin. A modification of the invention includes additional components of sand and gravel replacement bags at upper and lower ends positioned respectively within the body to permit tailoring of a filtration in response to aquarium needs.
