Fluval G3 Fine Pre-Filter Cartridge
The Fluval G3 Fine Pre-Filter Cartridge is designed for daily use with marine aquariums where suspended debris is minimal or it can be used as a polishing cartridge for standard or fresh water aquariums. The fine mesh will trap debris 75 microns or larger for unparalleled mechanical filtering results. Debris remains caught between each pleat until it is removed and rinsed. The effectiveness of the Fluval G3 pre-filtration process means that less solid waste is solubilised in the aquarium water for less waste accumulation.
