I forget the brand of uv because its not the one I usually use. It has the 3 u shaped lights coming out of it, and its only about 2 months old. I did move 3 weeks ago but ive checked to make sure all the temps and everything are the same. The only thing I can think is that the night time temps (since here in ga its just getting cold) have maybe dropped a few degrees, but the house is heated so its not that big of a drop. maybe I should leave the heat light on at night? He are and acted fine the first 2 weeks. Ill try to post pictures later, I dont have a camera but my sister is bringing me hers.
