my albino leopard gecko

Question
I recently bought my gecko from a pet store. I have a undertank heater, a place he can go hide, and a hot and cool side in the tank i was just wondering why i get so much condensation on the inside that i can't see through it and how i can get off and keep it off. The tank stays at about 88-90 degrees during the day time and about 75 degrees at night your help would be greatly appreciated

Answer
 The humid environment is great for the gecko.  Usually that means that your room is very dry and the difference in humidity causes the condesation.  Too dry a room is not good for you, you may want a humidifier in your room.  Another thing is air movement in the enclosure.  Is it vented enough?
