That's what I do too, laying flat on the floor, resting against the passengers seat. The danger is that the tank becomes a projectile in case you hit something.I lay mine down in the back seat, wedged between the seat and the backrest.
Scary story, but true, if the valve has an opportunity to open you better strap that beast in. I bought a tank that came with a black protective collar, even if the tank rolls or bumps it will not open or break the valve.LOL, hate to admit it but I can tell you how to not transport it!!!!!!!!!!!!!!!
Thought my tank was empty. That was the first mistake. The reg was messed up and it wasn't completely empty. Layed it down on the floorboard of the rear seat behind me. Didn't secure it, that was the second mistake. Had to come to a quick stop on the exit ramp of the expressway and it rolled, the valve bumped into the front seat and amazingly opened. It was winter and all windows were up, Co2 was spewing into the car. I tried reaching for the tank to shut off the valve while trying to keep from having a wreck at the same time. That didn't work. As I was feeling very, very dizzy I had one last clear thought, OPEN THE WINDOW DUMMY!!!!
The tank always goes in the trunk now...........SECURED so it doesn't roll!!!!
I'd agree... poor fish. :fish1:Those who say watch your fish to determine if you have enough CO2 in your tank................................From personal experience I don't believe the fish appreciate that very much!
