Dophin Internal Filters

The Dophin Internal filter is a heavy-duty filtration system delivering powerful mechanical, chemical, and biological (some models) filtration, which produces crystal clear water in both fresh and marine aquariums.

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.
