This is my leopard gecko tank. I have 2 leopard geckos inside 1 male and 1 female. I'm using a 100w basking bulb during the day and I have a night time lamp. Is this setup ok? The white stuff on the carpet is vitamin powder from crickets that I have to clean up. Also I have a 16watt heating pad that should take up just under half the tank, should I use a lower wattage lamp during the day when I put my heating pad on.
