It funny everyone in calgary is looking to dehumidify. Prior to the installation of my fish tank I could barely get the humidity in my house above 20%. It was destroying the hardwood, all the wood cabinets were drying out. I actually installed a new humidifier to get the humidity in the house up.

once I installed my 180 the humidity in the house went up to 35% and is fairly steady at that. My top-off bucket needs to be filled ever second day, so I am putting 2.5G of water in the air and my house is much better for it.

Calgary is so dry in the winter I am shocked to hear people say humidity is an issue. In vancouver, mtl and Toronto I fully understand the humidity issue but its interesting to hear people having the issue in calgary. That being said I do have an air exchange unit on the house so it may be solving any humidity issues without having a humidity fan.
