Steve- You are right that is their job, and they do it too well it seems.
Love of ANimals- You know, I never thought about that.
PridgNYC- Yes, both bulbs are very important to our turtles' health.

I hate to admit this, but Wednesda night, I put my turtle into a 5 gallon tank, removed the heater and UVB light, because I believed her!! I don't know what I was thinking. Then, yesterday, I put the UVB light back on, but left out the heater because our house is easily in the low 70's (have our heat on), and Ollie seems perfectly happy. I am going to put him back in the 10 gallon when he is bigger, because it is very hard for me to clean that tank by myself, and it is easier for me to do the 5. When he gets really big, I am going to buy the 55 gallon, and some sort of syphon, that way I will be perfectly able/ capable to clean that big one all by myself.
I should have listened to my gut, what I read here, and from other knowledgeable sources, but the person sounded so sure of their advice, I got confused and listened to the wrong place of information. Needless to say, lesson learned. Always listen to the majority, not the minority, for the majority surely are the correct group based on collective reasoning.
Thanks again.
