WP‑638H – 500 l/h cascade filter

This cascade filter is intended for keepers of aquariums between 40 and 112 litres who want to free up space inside the tank and change filter media without pulling the unit out of the water. It hangs on the outside of the tank, so the aquarium interior stays available for décor, substrate and livestock.

Why it matters

• Space saving: the slim body (14.9 x 8.3 x 19.1 cm) fits narrow spaces and keeps the tank interior clear, unlike internal filters.
• Low power consumption: the unit draws 6.8 W, which keeps running costs low over time.
• Surface skimmer: a built-in skimmer draws off the water surface to keep the top layer clean.
• Cartridge flexibility: the filter can be fitted with different cartridges, so biological or chemical media can be added or swapped depending on the setup.

What it works with

The filter is designed for aquariums of 40–112 l and suits tanks where a compact external solution is preferred over an internal unit. Its 500 l/h flow and cartridge options allow the filtration to be matched to the tank size. Fill the filter with water before starting it up.
