Best Lily Pipes for Canister Filters (2026)
FZONE 17mm Glass Lily Pipe Kit with Inflow Outflow for Aquarium(16/22mm)
Hand-blown borosilicate glass inflow and outflow in 17mm for 5/8 inch ID (16/22mm) tubing, with a two-head spring brush. A clean default for mid-size canister filters.
LINLAN 304 Stainless Steel Lily Pipe Inflow and Outflow with Mini Aluminum Alloy Pipe Holder, 360° Rotatable Outflow, Fits 1/2 Inch ID Filter Hose, for Rimless Aquariums (1/2")
304 stainless steel inflow and outflow for 1/2 inch ID hose with aluminum rim clips for glass up to 12mm thick. Freshwater only.
Lily pipes replace the green plastic inflow and outflow that come with a canister filter. The outflow spreads water in a wide, gentle fan instead of a jet, which suits planted tanks, and clear glass all but disappears in a rimless scape. The single most important spec is tubing size: most sets come in 13mm for 1/2 inch ID (12/16mm) hose and 17mm for 5/8 inch ID (16/22mm) hose, and a mismatch means a leak or a pipe that will not seat. Glass looks best but breaks if dropped and needs regular cleaning with a long brush, since biofilm shows quickly. Stainless steel is nearly unbreakable and hides dirt, but it is opaque and usually freshwater only. Skimmer inflows pull the surface film off the water as well, which helps with oily film in tanks with heavy feeding or liquid fertilizer. This guide compares glass kits in both common sizes, two skimmer sets, a budget poppy-style set and two stainless options.

#1Hand-blown borosilicate glass inflow and outflow in 17mm for 5/8 inch ID (16/22mm) tubing, with a two-head spring brush. A clean default for mid-size canister filters.
Fit for the job 9/10 · Features and specs 8/10 · Build and materials 8/10 · Value 7/10

- + Precisely cut intake slits at the end of the inflow, with room to fit a shrimp guard
- + Spring brush included, which you need from the first month for glass pipes
- - Only fits 5/8 inch ID hose, so 1/2 inch filters need the 13mm version
- - Glass pipes break if knocked while cleaning or rescaping
#2304 stainless steel inflow and outflow for 1/2 inch ID hose with aluminum rim clips for glass up to 12mm thick. Freshwater only.
Fit for the job 8/10 · Features and specs 8/10 · Build and materials 8/10 · Value 8/10

Fit for the job 8/10 · Features and specs 9/10 · Build and materials 7/10 · Value 7/10

- + Rotating base sets the split between surface and lower intake
- + Removes oily surface film without adding a separate skimmer to the tank
- - Acrylic float parts are bulkier and more visible than a plain glass inflow
- - Skimmer moving parts need more cleaning than a fixed pipe
#4Glass lily pipe inflow and outflow for 5/8 inch ID (16/22mm) hose with a long-bristle cleaning brush. The lower-priced glass option in the larger size.
Fit for the job 8/10 · Features and specs 8/10 · Build and materials 7/10 · Value 8/10

Fit for the job 8/10 · Features and specs 8/10 · Build and materials 7/10 · Value 7/10

- + Glass adapter included for small 9mm ID hoses on mini canisters
- + Floating skimmer inflow clears surface film in small tanks
- - Too short for standard-height tanks of 16 inches or more
