Chihiros Glass Lily Outflow Pipes are designed for external canister filters only.

Product Description

Lily Pipe creates an ideal water flow for the growth of aquatic plants.

By using Glass Lily Pipes in conjunction with clear filter tubing, you can practically make your filter invisible inside the tank, having an unobstructed view on the Aquascape.

Product Specification

** Size selection based on canister filter inlet / outlet.

**Photos are for illustration only. Outflow pipes come with only one suction cup design.

The unique shape of the inflow and outflow sections can gently adjust water flow without placing burden on water intake.
Used with Outflow Poppy Glass, it creates water flow suitable for keeping fish that prefer gentle water flow, such as betta and killifish, in an aquatic plant layout.
Depending on the placement of the outflow pipe, the water surface ripples adequately and provides aeration and a shimmering effect with a metal halide lamp.
