I decided to set up my tub today, a day in advance before I planned on picking up my new ball.
I set up everything, and waited a few hours so my UTH could get hot. I have 12 holes on one side, and 12 on the opposite side. Nothing else was done to the tub. I poured water into the dish, water cool but close to room temperature now. The UTH is at 92 degrees currently. My tub? Not so much haha.
I'm not sure of ambient temperatures, but it is on the cool side, and I don't have any heaters unfortunately. And my humidity is really bad? Any help would be great.
