Capture large particles and debris with the Fluval FX5 Aquarium Filter Foam Block for an effective mechanical filtration, the crucial first stage in the filtration process. The Fluval FX5 Aquarium Filter Foam Block is custom fit to prevent bypass, it has a pore size that allows efficient water flow with less clogging for long-lasting filtration. The Fluval Aquarium Filter Foam Block can be used for fresh or marine water aquariums.

Biological, chemical and mechanical filter media for the Fluval G FiltersReplace exhausted chemical media for optimum aquarium water qualityDifferent chemical filter cartridges allow custom aquarium filtrationMaintain Fluval G filter performance for optimum aquarium water quality. Wide selection of premium-quality replacement filter media allows flexible management of your specific aquarium needs. Keep on top of scheduled media replacement by programming a reminder for biological, chemical and mechanical filter maintenance.Fluval G-Nodes High-porosity ceramic bio-media feature a complex pore system where nitrifying bacteria, crucial for efficient biological filtration, will thrive. Distinct shape allows more bio-media to fit within the Fluval G filter baskets for enhanced biological nitrification. 1.25 Liters.Mechanical Pre-Filter High-capacity pleated mechanical filter cartridge traps significantly more suspended debris than conventional mechanical filter foam. Designed for daily use, this "no by-pass" cartridge traps debris between each pleat for effective mechanical filtration in freshwater or marine applications.Fine Pre-Filter Cartridge Fine mesh mechanical filter cartridge traps debris 75andmicro;m (micron) or larger for unparalleled mechanical filtration. It is designed for daily use with marine aquariums where suspended debris is minimal but as an occasional polishing cartridge for standard or freshwater aquariums. Designed as a "no by-pass" system, debris remains caught between each pleat until cartridge is removed and rinsed.Phosphate Cartridge Rapidly remove phosphate ions from marine or freshwater aquariums. Phosphate is irreversibly bound and will not leach back into aquarium water. Versatile Phosphate Cartridge can be used continuously to combat persistent phosphate problems or as a quick solution to reduce occasional, elevated phosphate levels.Nitrate Cartridge Effectively remove excess nitrate ions in freshwater aquariums. Nitrate is irreversibly tra
