Not an expert about bators as this is my first time and I did build my own too. I wonder if you got stryofoam boards, like they use in packaging and fix them around the outside of three sides of the aquarium to help with heat loss. I see them occassionly on Craigslist for free. Not sure about the temperture drop maybe some one with more experience can comment on. Good luck with your four.
