Q. My turtle has a uva / uvb blubs but is that enough to heat up the water for her?
A. Those bulbs are not used to heat the water!! You should place it in a spot where the turtle can "bask" in it. They are designed to provide lighting and heat in a specific spot for when they are out of the water. They are used as a substitute for the sun as most household lights do not give off any uva/uvb rays and turtles need those types of rays. Setting the tank next to a window will also not help as most windows filter those rays. If your turtles are indoors they need this lighting. Do not use the petstores for advice unless you find a reptile specialty petstore. Most employees are the big chains are just there for a paycheck and will tell you/sell you whatever you will buy. Reptile stores want what is best for your turtle. You could also seek out a veterinarian that specializes in exotics and they are more likely to help you and many will test your bulb for free and have them in stock.
A. I personally don't know too much about turtle to tell you but I would recommend that you call or visit your local pet store. (Petco, or Petsmart). They have care sheets in store that can explain what exactly to get and I'm sure there will be an assosciate there or on the phone that can help you. They're normally extremely friendly about that kind of stuff. I work at a pet store right now and when I get those types of questions there's always at least one person in the store that can tell you the answer.
