Pet Worx WXI-800 Internal Aquarium Filter – 800 LPH (150–200L Tanks, Freshwater & Marine)

The Pet Worx WXI-800 is a fully submersible internal filter moving up to 800 litres of water per hour, formulated for aquariums between 150 and 200L. It's suitable for both freshwater and marine setups, and combines strong turnover with a genuinely quiet running profile — no easy feat for a filter putting out this much flow.

Inside, a coarse black sponge sits in interlocking compartments for easy pull-out cleaning, and the shaft itself is high-durability ceramic, built to handle continuous heavy-duty use. A maximum head height of up to 1.2m gives you flexibility on where the outflow sits in the tank.

Two included attachments extend what the WXI-800 can do: a spray bar for wider water distribution and surface agitation, and a Venturi tube diffuser for optional air bubble aeration. Run it without any filter media and it doubles as a directional powerhead for extra circulation.
