Canister filter return flow straight through a plastic nozzle looks utilitarian and can blast plants and substrate with unwanted turbulence. Dymax Lily Pipes spread that return flow into a gentler, more even current while doubling as a genuinely attractive piece of in-tank hardware — available in stainless steel or crystal glass, with or without a built-in surface skimmer.
Why Aquascapers Use Lily Pipes
A lily pipe's curved shape and wide outlet diffuse a canister filter's return into a broad, gentle current instead of one forceful jet, reducing stress on plants and fish while still keeping water moving. They're also simply better-looking than a stock plastic nozzle, which is why they've become a staple in serious aquascaping setups.
Stainless Steel vs. Crystal Glass
- Stainless Steel — highly durable, resistant to chipping, and a clean industrial look that suits modern aquascapes.
- Crystal Glass — a nearly invisible, disappears-into-the-tank look that lets the aquascape itself stay the visual focus, at the cost of being more fragile than steel.
Standard vs. Surface Skimmer
Standard lily pipes handle return flow only. Surface Skimmer versions add a slotted intake that pulls in the oily, dusty film that collects on the water surface — a film that blocks light and looks cloudy from above even in a well-filtered tank — routing it through the filter along with the regular flow.
Choosing a Diameter
Both materials come in 12/16mm and 16/22mm diameters. The larger 16/22mm size suits bigger canister filters running higher flow rates; 12/16mm fits most standard planted tank canisters.
