Setup
Follow these steps to properly set up your Aqueon QuietFlow 10 E Internal Power Filter:
- Unpack Components: Carefully remove all components from the packaging. Ensure you have the filter unit, filter cartridge, bioholster, and any included clips or suction cups.
- Install Filter Cartridge: Open the filter unit and insert the Aqueon Small replacement carbon cartridge. Ensure it is seated correctly. The filter also includes a coarse media sponge for additional mechanical filtration and a bioholster for beneficial bacteria.
- Position the Filter: The filter can be installed using either the provided suction cups for frameless aquariums or hanging clips for framed aquariums. Choose the method that best suits your tank. Position the filter so that the water outlet is submerged but close to the water surface to ensure proper water circulation and aeration.
- Submerge and Plug In: Fully submerge the filter unit in the aquarium water. The auto-start pump requires no priming and will automatically restart if power is interrupted and restored. Once submerged, plug the filter into a grounded electrical outlet.

Maintenance
Regular maintenance is crucial for the optimal performance and longevity of your filter and the health of your aquarium.
- Filter Cartridge Replacement: The Aqueon dual-sided carbon cartridge should be replaced every 3-4 weeks to ensure effective chemical filtration and removal of odors and discoloration. Use only Aqueon Small replacement cartridges.
- Sponge Cleaning: The coarse media sponge, which provides mechanical and biological filtration, should be rinsed periodically in old aquarium water (during a water change) to remove accumulated debris. Do not rinse with tap water as chlorine can harm beneficial bacteria.
- Impeller Cleaning: Periodically check and clean the impeller and impeller well to prevent blockages and maintain consistent water flow.
