The Greenosis Glass Poppy Outlet Lily Pipe 17mm is a premium aquarium outflow pipe designed for larger aquariums using 17mm filter hoses. Crafted from high-quality transparent glass, its distinctive poppy-shaped outlet creates a gentle circular water flow that improves circulation while maintaining a clean and elegant aquascape appearance.
Unlike conventional outflow pipes, the poppy outlet design generates broad and even water movement across the aquarium surface. This helps improve oxygen exchange while promoting better distribution of CO₂, nutrients, and heat throughout the aquarium. The smooth flow pattern is especially beneficial for planted aquarium setups, helping support healthy plant growth without creating excessive current.
The Greenosis Glass Poppy Outlet Lily Pipe 17mm is ideal for larger freshwater aquariums, nature aquariums, aquascaping layouts, and high-tech planted tanks using external canister filters. Its crystal-clear glass construction blends seamlessly into rimless aquariums, creating a minimalist look while enhancing filtration performance and overall aquarium aesthetics.
