I'm assuming you have a carbon filter in one or both rooms? If so, make sure it's not on the floor. c02 is heavier than o2 so if your filter isn't mounted more towards the ceiling of your room that's probably why you're using so much. It's getting sucked into and through your filter. I have a 50 lb tank and it's still next to full. Currently it's only feeding one room but it's set to 1750ppm. It's going on 4 weeks and it will definitely last me through my entire grow, maybe my next.
