WP‑628H – 400 l/h cascade filter

This cascade filter is intended for hobbyists running 30–70 L aquariums who want to keep filter media outside the tank and free up interior space. Its slim 12 x 4.5 x 14.5 cm body fits into narrow spots, and the cartridge chamber can be loaded with biological or chemical media, which the supplier notes helps keep water clear.

Why it matters

• Low power draw: 6 W consumption keeps running costs low over time.
• Surface skimmer: the built-in skimmer draws off the water surface to help keep it clean.
• Swappable cartridges: the filter accepts interchangeable filter inserts, so media can be changed to suit the tank.
• Simple maintenance: the supplier describes the filter as easy to clean, and it works without removing it from the water.

What it works with

The filter is matched to freshwater and marine tanks in the 30–70 L range, and it is commonly used in nano aquariums. Its 400 l/h flow rate suits this tank size. Water clarity also depends on feeding habits, stocking density and substrate, so the filter should be combined with appropriate stocking and feeding practices.
