Activated carbon is great for freshwater aquarium filtration. It has the ability to not only visually clear the water; but trap pollutants in the pores of the carbon so they do not enter the water. This filter cartridge will remove ammonia; nitrites; odors and other harmful toxins from your aquarium to keep it healthy. It has a poly-fiber floss barrier which screens out particulate matter and debris for an extra layer of protection. Within 24 hours you will see a drastic difference in the water quality.
Each filter cartridge is perfectly measured to fit into the Cascade 150 / 200 Hang On Filter tray without any gaps preventing debris and contaminants from entering back into the water. This filter cartridge is suitable for both freshwater and marine environments. When used together; the Cascade 150 Model CPF3 / 200 Model CPF4 Filters and Cascade filter cartridges provide maximum protection against water pollutants from harming your fish.
