Hey guys, as some may know myself and my boyfriend just got our Belle a few days ago. The tank we got from her old owners is a 40 gallon and came with a lamp and heating pad that was way too small. Today we went and got a 12 by 8 UTH and the bulb in the lamp is 100W. The top to the enclosure however is grated and we're having a hard time keeping the heat gradient right. The cool side is 78 and the warm side is around 82F. We've tried plastic wrap on the lid and are now using tin foil as we heard that can help with keeping in the heat and humidity especially with using a lamp. Does anyone have any suggestions for ways we can turn up the heat in her tank? We have Cyprus Mulch as a substrate, two hides for her, a large water dish and a large branch in the center of her enclosure. The other black thing on the side of her enclosure is the old heating pad. It's not turned on, just there for safe keeping. A picture is below: http://oi61.tinypic.com/2cxc1ms.jpg
