FZONE 16 feet Aquarium Co2 Proof Tubing 3/16'' ID Black Food Grade Air Line Tubing

Best Co2 hose on the market. This is the perfect tubing for any co2 setup its super durable and is easy to straighten which is normally an issue with these types of tubing. Super easy to use, standard size fits up perfectly to my inline diffuser. Obviously since it's from FZone its great value, and now worry about leakage.

I used the Fzone air line hose for my Co2 regulator and its works great. No complaints.

These work greatly!

Excellent quality CO2 tubing. Also comes with four suction cups. CO2 tubing is thicker than aquarium tubing, stick the cut ends in boiling water to soften it up and you'll get a tighter fit on your bubble counters diffusers etc. you can also use boiling water to shape the entire tube if you want. Whenever I have CO2 tubing that gets creases in it I'll just stick the whole thing in boiling water and then lightly stretch it across the room and let it cool and it takes the creases out.

Definitely worth the money. Also if you have your tank lower than you aquarium make sure to get check valves

Works just fine but mine came with writing on the tubing about 1 1/2 feet spaced apart, I just cut and placed the part that was gonna be seen in the tank with a piece with no writing on it and connected the rest with a check valve where it can’t be seen behind the tank.

I've been using CO2 in my aquarium for a while now and constantly I would have some issues with the CO2 leaking. I started researching and realized there are CO2 tubing that's meant for aquarium setups. I ordered this and having used it for several weeks now it is definitely worth the money to invest in. The air line tubing I was using before, while doing its job for the airstone, it definitely didn't stand up to be used for CO2 system. I was happy with the packaging and the length of tube provided. It took some time to get the tube straightened as it's made of thicker plastic but overall no leaks and I couldn't be happier of this simple purchase that's made a this hobby more enjoyable and less stressful to think that my CO2 would leak.

I’ve used this hose to set up multiple system. Enough hose to get any system going and plenty of suction cup mounts included. Can’t beat the price for the quality!
