I have all the doors shut, dehumidifier running, fire charging, a small fan heater going and a big fanny circulating the air as well as using the vacuum thing. Problem I am finding with everything being so closed in is the smell is getting pretty ripe so I am having to do a quick fresh air change every hour or so. That and I am feeling uncomfortable sitting in the heat.
I am sure I am averaging a spill every month, always from a different tank and always something different. There is brown patches everywhere in my house now.
