• 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.(the filter material not included)
• The water trickles through the trays, keeping the filter wool wet but not completely submerged, allowing aerobic bacteria to grow and aiding biological filtration. The water returns to the aquarium like rain.
• 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.
• Other canister filter ceramic noodles and have little effect, as they are completely submerged.

Package included:

• 1 x Upper Box Filter + 1 x water pump(the filter material not included)
