Ok, so I'm trying to set up a 120 lb co2 tank at my friend's place. I got it rigged up for what I thought was a slow leak through some pvc tubing with holes in it, the pressure reading was at about 4 psi, & the tank valve & the regulator valve were mostly closed. Tank pressure read full at the top of the green on the gauge since the tank is indeed full. Now, this was running for about 4+ hours when my friend called me & said he passed out from co2 poisoning on the 3rd story of his house? Is this possible? The room is in the basement, doesn't co2 sink since it's heavier than oxygen? I did kind of have a headache I left after regulating the tank. We're growing in a bathroom, hard to get exact square footage since the room is cut at weird angles. it's maybe equivalent to 10' x 5' x 7'. There is currently no exhaust in the room, do I not need to run the tank that long? I used the co2 calculator sticky link after the fact & it said that I could fill the room to 1500 ppm in about 15 mins or so. Could 4+ hours of my tank running fill a 3 story house with co2?

Sorry for the long run on, I hope someone experienced can give me some advice here. Thanks.
