I like to use the daylight bulb during the day and the nightlight red bulb on at night just because I love the way the daybulb looks in the tank during the day for daytime veiwing, and they way the red light looks great at night for nightime veiwing.
Oh and the links I used in the first thread post, they were just examples to show you the brand and the type of bulb I use. I don't actually use only a 25 watt lightbulb hehehe
My temps and humidity are actually pretty good, I have a dimmer for my UTH and a dimmer for my heat lamp. I monitor both temps actaully way too much. I make sure they're perfect all the time! As for humidity, I mist a few times daily and keep a wet towel (not dripping wet) on top of the lid screen. That seems to work well.
