Keep your pond aeration system running at peak performance with the OWS Riser Tube, engineered to prevent diffusers from sinking into mud and debris. Over time, diffusers can settle into sediment, reducing oxygen output and forcing you into unnecessary maintenance cycles. The riser tube solves this by elevating your diffuser above the bottom, ensuring maximum efficiency and longevity. Constructed with durable, water-resistant materials, this riser tube integrates seamlessly with OWS self-sinking and molded bases. No tools, no hassle-just slide the riser into place and enjoy worry-free aeration. By keeping diffusers positioned properly, your pond benefits from more consistent oxygen transfer, healthier water, and less muck build-up over time. Whether you're a landowner, property manager, or pond care professional, the OWS Riser Tube is a small investment with a big impact: fewer clogs, less downtime, and a system that performs the way it was designed to-every single day.
