c02 50 lb tank question

[_Dream_chaserz]

I Noticed the c02 tank running out quickly than normal. I usually have the tank for 9 days. However the last 2 refills, I noticed the 50 lb tank only last me for 3-4 days @ 1200 ppm (when lights are on). I have 2 exhaust fans flitering the air in my room constantly running to filter the smell. Is my tank running out quickly because of my exaust fans ?? or what else could be the problem? PS Currently using Autopilot Greenhouse Master controller for c02 readings. Please advise????

Do you have pics of your co2 setup? I have co2 gauges and want to see how yours is setup.
