Penn Plax Cascade Canister Filters - Aquarium Filter & Fish Tank FilterCreating and maintaining a healthy, well-balanced aquarium is hard work. That's why aquarium owners deserve to take a lot of pleasure in watching their underwater community thrive. You can make sure your aquarium always looks its best with a quality filtration system featuring Penn Plax Cascade Canister Filters. Murky and polluted water can hide your great accomplishment and negatively impact the health of the animals and plants in your aquarium. Penn Plax Cascade Canister Filters will keep your water clear by delivering powerful mechanical, chemical and biological filtration. Here's how this powerful fish tank filter works: the floss pad removes fine particulate matter, while the activated carbon media removes toxins and impurities from the water. Together these two aquarium filter systems help establish a cleaner and healthier environment for your fish and other aquatic life. The coarse sponge supports the final filtration stage in this fish tank filter by providing abundant surface area for bacterial growth. The bacteria digest waste, excess food and harmful ammonia and nitrates. The Penn Plax Cascade Canister Filters are constructed for easy setup and use. This durable aquarium filter is equipped with quick-disconnect tubing connectors that can also control the filter's flow rate. To ensure a secure and water-tight fit, this dynamic fish tank filter utilizes four locking clamps along with a motorhead equipped with an integrated O-ring. The filter media is included with each aquarium filter. Once everything is fitted and locked into place, you can use the push-button self-primer to start up the filter. With this filter in place, you can sit back and enjoy all the activity going on in your marine or freshwater aquarium.
