Only thing I can find on your filter, if you are using the stock one is this...
Powerhead: 400 L/hr
Filtration: 1 x Carbon Cartridge with Filter Wool + 1 x Sponge Pad + Ceramic Noodles
However, the main attraction of the Aqua One Aquastyle 380 Aquarium is the wet and dry filter system built into the hood, which provides excellent biological, mechanical and chemical filtration and reduces the technical equipment in the tank. This system is biologically far more capable than the internal filters normally found on small to medium sized aquaria, due to the higher oxygen intake capabilities of an open system compared to those belonging to a submerged system. Maintenance of the filters is child's play. No immersing your hand in the aquarium to remove difficult internal filters. You simply open the lid and (with the pump switched off) remove and clean the media cartridges. This style of filtration has also proven to be extremely efficient on salt water systems for the removal of water pollutants and the maintenance of good water quality in your tank.
