Definition of Internal Filters as it relates to Pets, Fish Tanks
Internal filters are devices designed to maintain and enhance water quality within fish tanks. They work by drawing in water, passing it through a mechanical filter medium to remove physical debris, then pushing it back into the tank.

These filters promote a healthy environment for aquatic life, making them an essential component of any fish tank setup.
