Fluval G Series Filtration Media Fluval G Series Filtration Media – FLUVAL G6 / G3 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. Fluval G6 Fine Pre-Filter Cartridge – The Fluval® Fine Pre-Filter Cartridge is designed for daily use in 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 75μ (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 Fluval® G’s 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. FLUVAL Phosphate Cartridge – The Fluval® Phosphate adsorbing cartridge will rapidly remove up to 3900 mg of phosphate ion from marine or fresh water aquariums. FLUVAL Nitrate Cartridge – The Fluval® Nitrate adsorbing cartridge will remove up to 24000 mg of nitrate ion in fresh water aquariums. Nitrate concentration should not exceed 20 mg/L in freshwater aquariums. Planted aquariums require approximately 5 mg/L of nitrate as a source of nitrogen for healthy plant growth. FLUVAL Tri-X Cartridge – Fluval® Tri-X 3-in-1 cartridge is for use in the Fluval® G Filter. Combining the binding power of Fluval® G phosphate, nitrate and carbon, Tri-EX is an all-in-one pollution management solution for freshwater aquariums. With the continued use of Tri-EX, nitrates, phosphates and organic pollutant remain under control. Fluval Chemical Cartridge – Fluval G Re-usable Chemical cartridges are for use with the Fluval G advanced filters. The cartridges are designed to hold most loose or granulated chemical filter media down to 0.2mm in diameter and provide maximum versatility for the hobbyist.
