The Hagen Marina Bio-Carb Cartridge 3 Pack are designed to replace the filters on all 3 slim filter models.
Ideal for tropical fish, they combine activated carbon and ceramitek in 1 cartridge for a healthy aquarium.
The activated carbon effectively removes pollutants and odours, while the ceramitek optimises biological filtration.
The easy to use cartridges should be replaced every two weeks.
Never replace all filter cartridges at the same time in order to ensure constant presence of beneficial bacteria.Approximate Dimensions (Packaged):
