The floss pad removes fine particulate matter, while the activated carbon media removes toxins and impurities from the water, leaving a cleaner and healthier environment for your fish and other aquatic life. The coarse sponge makes for an abundant surface area for proper biological filtration by promoting bacterial growth to effectively remove waste, excess food and harmful ammonia and nitrates.

This durable aquarium filter is equipped with quick-disconnect tubing connectors that can also be utilized to 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.  Filter media is included free with each canister filter.
