Fluval G3 Canister Filter Fine Pre-Filter Cartridge
The Fluval Fine Pre-filter is a daily use cartridge for the Fluval Advanced Filter Cartridge 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. For extended use it is recommended the cartridge is cleaned at least every 2-3 weeks. The effectiveness of the Fluval's 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.
