Easy Cartridge Replacement Steps
Remove Old Cartridge
Turn off your power filter and carefully remove the old, dirty cartridge from the unit. This prevents debris from being stirred back into your clean tank water.
Rinse New Cartridge
Briefly rinse your new Top Fin Silenstream cartridge under cool running water. This simple step washes away any loose carbon dust before it enters your aquarium.
Seat Correctly
Press the new cartridge firmly down into the designated slot until it sits flush. Proper positioning ensures water passes directly through the filter media without bypassing it.
Install & Restart
Slide the new, rinsed cartridge into the empty slot in your power filter until it clicks into place. Turn the filter back on and enjoy your refreshed aquarium.
