Cascade 300 GPH Hang On Replacement Cartridges, 3 Pack

The Penn Plax Cascade 300 GPH Filter Cartridges with Activated Carbon are designed to improve the quality of your aquarium water and keep your fish healthy. This replacement filter is compatible with the Cascade 300 GPH hang-on power filter and will last 6 to 12 weeks under normal conditions.

Activated carbon is an excellent choice for freshwater aquarium filtration. It has the ability to not only visually clear the water, but also trap pollutants in its pores, preventing them from entering the water. This filter cartridge will remove ammonia, nitrites, odors, and other harmful toxins from your aquarium, keeping it healthy.

The filter cartridge features a poly-fiber floss barrier that screens out particulate matter and debris, providing an extra layer of protection. Within 24 hours, you will notice a significant difference in the water quality.

Each filter cartridge is perfectly measured to fit into the Cascade 300 Hang on Filter tray without any gaps, preventing debris and contaminants from re-entering the water. This filter cartridge is suitable for both freshwater and marine environments.

When used together, the Cascade 300 GPH Filter Model CPF5 and Cascade 300 filter cartridges provide maximum protection against water pollutants, ensuring the health and well-being of your fish.

Sold in a 3-pack, these genuine Penn Plax filter cartridges are the perfect solution for keeping your tank clean and clear. The activated carbon in the cartridges can effectively remove odors and discoloration by trapping the pollutants in its pores.

The poly-fiber floss barrier of the cartridge screens out particulate matter and debris, maintaining a clean, clear, and healthy environment for your aquatic life.

No assembly is required, making it easy to install the cartridges into the interior compartment of your hang-on filter. These cartridges are suitable for both freshwater and saltwater tanks.

The internal filter cartridges come in either blue or black plastic, both of which are identically measured to fit the Cascade 300 filter tray without any gaps, ensuring that debris and contaminants cannot pass back into the water.
