Fluval G3 Tri-EX Cartridge
Fluval G3 Advanced Filtration Tri-X Cartridge combines the binding power of Fluval G phosphate, nitrate and carbon for an all-in-one pollution management solution for fresh water aquariums. With the continued use of Tri-EX, nitrates, phosphates and organic pollutants remain under control; the cartridge binds over 5000 mg of nitrate and over 600 mg of phosphate ion. The specialized mesh size of the carbon component maximizes the surface to volume ratio for optimized performance.
