1. i have a this temp gun http://www.amazon.com/Zoo-Med-ReptiT...o+med+temp+gun, it seems to be working good but i read that this one the pro exotics 2 is better
http://www.amazon.com/Pro-Exotics-In...=pro+exotics+2 my question , is it worth it to return the one i have and buy the pro exotics 2 or is there not that big of a difference in accuracy , my second question is , im switching from paper towels to aspen bedding , i am doing this because im having a hard time keeping up the humidity in my 30gal aquarium, how deep should it be ? i was thinking an inch to inch/half and i was planing on gluing or taping down the probe for the thermostat in the middle of the heat pad, im guessing it should be under the substrate but that leads me to the question of when i use my heat gun to test my hot spot should i go by what the surface of the bedding is or by the bottom of the cage under the substrate? and one last thing , read some post where people said that the put the probe for there thermostat between the pad and the bottom of whatever they where keeping the snake in , this doesn't make any sense to me because the probe for my thermostat is a round cylinder about the size of a aaa battery , is there some that have a flat probe ? if so to me it seams like between the bottom of the cage and the pad would not be a very good place for it. iv been asking a lot of questions sorry
