The Vevor bio pressure pond filter is designed to keep decorative ponds and fish ponds clean with a 1840 GPH flow-through rate and integrated biological filtration. It includes a 13W UV-C lamp with three timing settings to help improve water clarity and reduce pollution. Four filter sponges of varying densities help remove suspended particles, sediment, and organic matter. The pressurized design supports easy backwashing and simple maintenance with a top crank handle and turbidity indicator. Built from reinforced PP material, it also includes multiple adapter sizes for broad pipe compatibility.
