Upper Trickle Box Filter System. Trickle filters, also known as wet / dry filters for marine and freshwater aquariums. Water is pumped over a number of perforated trays containing filter wool or some other filter material. (pump not include) - The water trickles through the trays, keeping the filter wool wet but not completely submerged, allowing aerobic bacteria to grow and aiding biological filtration.
It consists of a fixed biological media over which sewage or other wastewater flows downward and causes a layer of microbial slime (biofilm) to grow, covering the bed of media. Aerobic conditions are maintained by splashing, diffusion, and either by forced-air flowing through the bed or natural convection of air if the filter medium is porous. Bio Medias are only really effective when they have water trickling through them. 6 Boxes: Fit Tank 1.3-1.8FT 9 Boxes: Fit Tank 1.8-2.2FT 12 Boxes: Fit Tank 2.2-2.7FT 15 Boxes: Fit Tank 2.8-3.5FT 18 Boxes: Fit Tank 3.5-4.0FT.
