I find Calgary extremely dry, even now in the summer my basement where my 250 G tanks is situated the RH is only 41%, upstairs on my main level where I have a 100 G tank it's 36% on average.
I would imagine if your tank is in a 'fish room' or a smaller foot printed area then it could be a problem, I just never thought about mold due to high humidity. I would agree, air movement is critical to ensuring good air quality.
My basement windows are completely clear and I would estimate my evaporation rate is about 12-14 Gal per week judging by the size and replenishment frequency of my ATO tank.
