First thing - I am running an auto disperse system. I set the ppm at 1800 and let the thing run. It was empty 3-4 days later. How long should a 20 lb bottle last in a sealed room? I figure it is more than 4 days????

Second thing - My Co2 monitor gives me a constant readout of current levels. I have read that ambient fresh air is around 300 ppm. My room with no enrichment was 1045 ppm this morn when I went in there!! It varies from 400+ppm to 800+ during the day?????
Isn't this odd? I have a gas burning central heating unit in the attic. The only thing I can think of is that it may be venting Co2 into the attic and it is making its way down to the living areas.
It seems quite odd to me though.
