Premium quality blue CO2 tubing for planted aquariums.
4mm internal, 6mm external.
This tubing is very different to all other types of on the market in terms of what it is made of - other brands do not use the right type and as a result the tubing becomes brittle and leaks gas. This tubing will last indefinitely - in fact we're still using the same tubing from about 6 years ago.
Fits all CO2 glass diffusers on our website.
Sold per meter so if you want 4 meters, add 4 to qty box.
Tip: To attach tubing to CO2 glassware, dip the end of the tubing in boiling water for 2 seconds, then simply push onto the glassware (easy peasy...!)
