kyarnkid,
well, i went out and bought another heater and it did not do the trick, unfortunetly i am still having the same problem. the only source of heat is a portable heater (new addition to the house was the garage, converted to a bedroom and never ran heating ducts) which i do not have on 24/7, so as the room temp drops so does my tank. i cant figure a cheap way to fix the prob. either. if you find a way let me know, sorry and thanks
