Description
This listing presents an Anti-Backflow Internal Aquarium Filter with seven selector labels: 4 W, 6 W, 15 W, 20 W, 25 W, 35 W and 45 W. No option is selected by default. The wattage labels identify the storefront choices. Before use, check the selected variation’s label and manual for electrical input, flow rate, suitable tank volume, dimensions and anti-backflow performance.

Select the exact variant
Choose a variation only after obtaining the exact label or manual for that model. Confirm voltage, frequency, plug, rated power, flow guidance, installation depth, tank-capacity range and required clearances. Do not infer those details from the wattage label, a similar pump or the main photograph. Check the selected variation’s voltage, frequency, plug type and certification for the destination before purchase or connection.
Electrical and wet-use checks
- Do not connect the filter until the delivered electrical label matches the intended power supply and destination.
- Follow the product-specific manual for placement, water level, priming, cable routing, cleaning and safe disconnection.
- Keep plugs and connections dry, use appropriate protected power arrangements and disconnect power before handling equipment in water.
- Do not operate a damaged unit, cable or plug, and do not rely on the “anti-backflow” descriptor as a verified safety control.
No claim is made here for filtration capacity, water clarity, quiet operation, energy efficiency or livestock suitability. Those depend on exact variant specifications and the aquarium setup.

What to check
Check the selected variation’s manual and packing list for package contents, accessories, product weight and exact technical specifications.
