Cascade Internal Filter Cascade 400 - Up to 20 Gallons (110 GPH)
The Penn-Plax Cascade Internal Filter by Penn Plax is designed for better filtration and aeration above and below the surface! The spray bar distributes water evenly over the water's surface to aid in aeration for healthier, cleaner aquarium water.
The Cascade Internal Filter provides crystal clear water for freshwater and marine aquariums, and is great for aquatic terrariums too. Activated carbon cartridge media is included for efficient chemical filtration of harmful chemicals, toxins, odors, discoloration and other contaminants. The carbon cartridge is easy to replace for simple maintenance. The internal sponge optimizes colonization of beneficial aerobic bacteria, which remove ammonia and nitrates for safe, healthy water. A large capacity internal filter cup lets you choose your own filter medium as well.
The pump head features adjustable and directional water flow. An included elbow fitting easily attaches the spray bar to the pump for even water return distribution. The filter may be placed vertically or horizontally. UL-listed for safety.
