What it does Rotates to set the flow direction for your sump or refugium, helping you tailor movement to your tank's needs. Keeps water moving where it matters, supporting healthier filtration and more stable parameters. Material and compatibility Made from durable, corrosionresistant plastic for longterm use. Compact design fits in tight sump compartments and works with standard aquarium plumbing used in most home setups. Size and performance Small, unobtrusive footprint designed to integrate with common tubing and fittings. Reliable, leak performance with smooth rotation for easy adjustment. What you get Quantity: 1 piece Use scenarios Refugium optimization: direct flow through macroalgae or associated substrates to enhance nutrient processing. Sump tuning: adjust direction to reduce surface splashing and noise while maintaining adequate circulation. Display tank refinement: finetune flow around rocks and corals for even, gentle movement without excessive turbulence.
