Fluval Underwater Filter Manual
Regular Maintenance - Media
CAUTION: Always disconnect all internal electrical accessories before placing hands in water.
As with all mechanical filtration devices, the filter media must be changed to provide optimum purifying performance. Although the impeller is self-cleaning, regular cleansing of the impeller well is recommended. Soap or detergents should never be used as traces left on equipment may stress or kill fish. Rinse thoroughly in lukewarm water.
