Meet the Pet Worx WXF‑1800UV, a high‑output external canister filter designed to deliver strong mechanical, biological, and chemical filtration for larger aquariums while keeping maintenance simple and efficient. With 1800 L/h of flow and a built‑in 9 W UV steriliser, it helps control waterborne algae and harmful microbes for clearer, healthier water in freshwater systems up to around 600 litres depending on stocking and bioload. The unit arrives ready to run with hoses, quick‑release taps, spray bar, and a full media stack so you can set up quickly and tune flow and direction for your aquascape or livestock needs.​

• Capacity guidance: For heavy bioloads or messy species, plan for higher turnover or supplemental filtration/aeration to maintain parameters.​

Common comparisons

• Versus lower‑flow WXF‑1200: the 1800UV provides higher turnover and built‑in UV, better suited to larger community setups and cichlid tanks.​
• Versus WXF‑2200UV: the 2200UV offers more headroom and flow for very large or heavily stocked systems if extra turnover is required.
