It is the same surgical-grade stainless steel construction as the 12\/16mm set: resistant to rust, scratches, calcium buildup, and the chemical environment of both acidic and alkaline planted tank water.\u003c\/p\u003e\u003cp\u003eThe larger 16\/22mm diameter accommodates the higher flow rates of bigger canister filters, maintaining the lily pipe outflow's circular surface agitation across a wider cross-section of return flow. For planted tanks of 50 gallons or more running a high-flow canister, the 16\/22mm set delivers the same benefit as the smaller size — clean surface movement for gas exchange and CO2 distribution — at the scale that matches the system's filtration output. The outflow lily pipe's flared bell design creates a circular surface current; the inflow pipe draws water from the lower tank into the canister for processing. Hose clips are included for secure connection at both ends.\u003c\/p\u003e\u003cp\u003eStainless steel lily pipes occupy the premium tier between plastic inflow\/outflow fittings and glass lily pipes. Plastic is durable but visually heavy and prone to discoloration. Glass is visually refined but fragile — a single contact with a hard object during cleaning or tank maintenance can shatter the pipe mid-build. Stainless steel is both visually clean and genuinely robust, with the additional advantage of calcium and chemical resistance that glass does not provide.\u003c\/p\u003e\u003ch3\u003eKey Features:\u003c\/h3\u003e\u003cul\u003e \u003cli\u003eSurgical-grade stainless steel outflow and inflow lily pipe set for larger canister-filtered planted aquariums\u003c\/li\u003e \u003cli\u003eSized for 16mm ID \/ 22mm OD canister filter tubing\u003c\/li\u003e \u003cli\u003eOutflow lily pipe creates circular surface agitation for gas exchange and CO2 distribution at higher flow rates\u003c\/li\u003e \u003cli\u003eResistant to rust, scratches, calcium buildup, acidic water, and alkaline water\u003c\/li\u003e \u003cli\u003eDurable premium alternative to both plastic fittings and fragile glass lily pipes\u003c\/li\u003e \u003cli\u003eIncludes outflow lily pipe, inflow lily pipe, and hose clips\u003c\/li\u003e \u003cli\u003eClean stainless aesthetic suited to mid-size and large Nature Aquarium and Dutch-style builds\u003c\/li\u003e \u003c\/ul\u003e\u003ch3\u003eIdeal For:\u003c\/h3\u003e\u003cul\u003e \u003cli\u003ePlanted tank builds in the 50 to 100+ gallon range running a larger external canister filter with 16mm ID \/ 22mm OD tubing, where a premium stainless steel inflow and outflow set is the right visual and functional upgrade over standard plastic fittings\u003c\/li\u003e \u003cli\u003eAdvanced aquascapers running a large Nature Aquarium or Dutch layout who want the cleanliness of a lily pipe visible in the tank without the glass breakage risk that comes with maintenance and water changes on a larger system\u003c\/li\u003e \u003cli\u003eHobbyists upgrading from plastic inflow\/outflow to stainless steel for better longevity, calcium resistance, and visual quality on an established large planted tank\u003c\/li\u003e \u003c\/ul\u003e\u003ch3\u003ePro Tips:\u003c\/h3\u003e\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eUse the same citric acid cleaning method as the 12\/16mm set.\u003c\/strong\u003e Calcium deposits accumulate faster on larger-diameter pipes at higher flow rates because more water volume passes the steel surface per unit of time. A monthly citric acid soak — diluted in water, brief soak, thorough rinse — keeps the 16\/22mm set visually clean and flowing at full capacity longer than relying on manual scrubbing.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eConfirm your canister filter uses 16mm ID \/ 22mm OD tubing — not 16\/22mm in another measurement convention.\u003c\/strong\u003e Some manufacturers label hose sizes by inner diameter only; others by outer diameter only. The 16\/22mm designation on this set refers to 16mm inner diameter and 22mm outer diameter. Measure your existing hose's outer diameter with calipers to confirm the 22mm OD before ordering.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePosition the inflow intake away from CO2 diffusor output.\u003c\/strong\u003e On larger tanks, there is more flexibility in equipment placement. Avoid positioning the canister intake directly in front of the CO2 diffusor — it will pull CO2 bubbles into the canister before they dissolve, reducing CO2 efficiency and increasing the chance of CO2 gas locks in the canister filter body.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003eOnline exclusive: this item is ordered in for you and is usually ready within a few business days.
