The ceramic can be replaced with another filler, such as activated carbon, when the aquarium has been treated. The filters in the Turbo Filter series are more powerful than other internal filters and are suitable for aquariums ranging from 250 to 350 liters. They filter and provide oxygen. The flow rate and direction are adjustable. Power: 22 W, capacity: 1500 l/h, warranty: 2 years. Manufacturer: Aquael, Poland. Distributor: UAB "Akvalita.".
