I am trying to plumb co2 across a room under the rug. I have two planted tanks on opposite walls and only one 10 lb CO2 tank. What is the best way of doing this? The owner of the LFS suggested that I should use that black drip line tubing that is used for irrigation so it will not pinch when people step on it. The tanks are about 10 feet apart.
I am concerned about three things:
Will the pressure of co2 in airline tubing or drip line stay at a similar or close pressure at 10 feet?
If I am using the drip line tubing, how should I make it air tight around the brass Y connector that separates the two lines. For those of you who haven't used drip line: it has the nasty tendency to stretch and stay stretched unlike our trusty airline tubing. I was thinking about just using a small hose clamp.
Is drip tubing even more permeable to co2 than airline tubing? So much that it is not even worth my time?
My other options are:
Use regular airline tubing all the way around the room instead of across it so I don't have to worry about people stepping on the line. My concern for this is that the length of the line could exceed 20 feet and that the pressure drop would be large.
Use some kind of pvc to go all the way around the room. I'm not sure what type of tubing to use for this. This is also the least desirable option because it is the most expensive.
Is there anyone that has had this same or a similar problem? I was unable to find any forum posts. Any other ideas?
