imo keeping a glass tank is not that difficult even w/o a thermostat.i am in the basement and its very cool down here,around 70 at all times.i have a glass tank almost on the floor and have takin the temps outside the tank and it is 67 to 69.with a uth and a dimmer,an d a inferred light on a dimmer the hot stays from 90 to 93 and cool is 81.humidity always above 48%.to the original poster stick with it,tinker until you get it right and if you cant ill be more than happy to buy your stuff from you or you can take it back,buy a tub that is not very pleasing to the eye.
