What we liked
- + Comes with 4 suction cups and 2 clear check valves, so the line can be fixed to the glass and guarded against back siphoning
- + Clear PU tubing lets you see gas moving through the line, and the listing describes it as low odor
- + Standard 4mm inner and 6mm outer diameter with resistance to pressure and folding, in a 16.4 ft length
Trade-offs
- - Listing gives no pressure rating in psi and no CO2 loss figure for the tubing
- - From a lesser-known brand, and clear tubing is more visible against a dark background than black line
