ANS CO2 U Glass Tube (15mm) for SG Planted Tanks

This 15mm U-shaped glass tube is the elegant solution for routing CO2 tubing over the tank rim without an unsightly drilled hole or a kinked plastic bend. It hooks the line cleanly over the glass edge, so your CO2-resistant tube runs down inside to the diffuser while the visible portion stays a tidy, transparent curve. On a planted display where everything is on show, that small detail keeps the rim looking deliberate rather than cobbled together.

Glass is the right material here because, like the CO2-resistant tubing it connects, it will not let CO2 permeate the way soft plastic can, and it stays crystal clear without yellowing in our warm, humid conditions. Being glass, it is fragile, so we suggest seating it gently and securing nearby tubing with a suction cup to stop strain on the bend. A periodic clean keeps algae from clouding the curve over time.

Find matching glassware and fittings under cleaning and maintenance. Our CO2 tubing guide, diffuser guide and beginner CO2 setup guide show how it fits the wider system.
