Why would anyone bash you? As far as I can see, you have a legitimate question.

Is it a glass tank? If so, I would insulate the sides and back with rigid foam insulation and partially cover your screen top. This will serve a few purposes....it will help trap in some of that heat, raisingt your ambient temps....it will help keep your humidity in the proper range...and it will give your BP a better sense of security since there won't be a bunch of light coming in from all sides. You can get the rigid pink insulation at any Home Depot/Lowes for a few bucks for a big sheet.

BTW...welcome to BP.net. Don't be afraid to ask questions...we were all noobs at one point in time.
