Fluval G3 Pre-Filter Cartridge

The Fluval G3 Pre-filter is a daily use cartridge for the Fluval G3 Advanced Filter and will trap suspended debris for effective mechanical filtration in fresh or marine applications. Designed as a no-bypass system, 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 and also makes the chemical and biological filtration components of the system more effective.
