Fluval Fine Pre-Filter Cartridges

The Fluval G 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 (micron) or larger for unparalleled mechanical filtering results. Designed as a no by-pass system, debris remains caught between each pleat until it is removed and rinsed. However, solid wastes can break down into soluble wastes and regular cartridge rinsing is recommended. The effectiveness of the Fluval Gs pre-filtration process means that less solid waste is dissolveed in the aquarium water for less waste accumulation and also makes the chemical and biological filtration components of the system more effective.
