So i was having issues with not enough humidity (cold dry winter here) in my tub 31qt and kinda used this idea from some one on this fourm but he/she used it on a glass tank with a screen on top but i applied it to a tub and seems to work fine, i just paper clipped(ones that actually hold clip) a towel and soak it in warm water and get it just damp enough were it wont drip water and pull it across half the tank and been doing this for 3 days now and have a steady humidity around 72.
