Fluval G series Pre Filter Cartridge
It is designed to trap suspended debris for effective mechanical filtration in fresh or marine applications. Its no by-pass structure means debris remains caught between each pleat until it is removed and rinsed. Fluval® G’s effective pre-filtration process means that less solid waste is solubilised in the aquarium water, which results in less waste accumulation and improved chemical and biological filtration efficiency.
For extended use, we recommend cleaning the cartridge at least every 2-3 weeks
