Aquarium glass lily pipes are elegant, transparent filter pipes designed for use with canister filters. The glass inflow pipe draws water from the aquarium into the filter, while the lily pipe outflow gently returns the filtered water, creating smooth surface agitation and natural flow thanks to its unique shape, ideal for planted tanks. Aquarium glassware blends seamlessly into the aquascape, offering a clean, unobtrusive appearance while promoting efficient and consistent water circulation.
