Yeah I was worried about the humidity now I am worried about maintaining heat... Could you recommend a good uth and a decent thermostat? Going to try to return this zoo med rheostat for twenty bucks and this crap uth for another twenty... My tank is accrylic so I feel a good uth that adheres would help with heat...also if a space heater is out of the question and ambien air will always be sixty eight will a lamp be necessary... Then again a better question would be can a uth put off enough heat in that aambien air temp?
