Hello again,
I have a heat mat under the warm side as well as a heat light and get the temperature up above 80 degree. I've covered 3/4 of the mesh with aluminum foil. My tank also is more deep than it is long so the option to have gradient temperatures is practically impossible. I keep reading about 80-82 (coolside) and 90-92 (warmside), what can I do to achieve that? Also, what do I need to do at night for a good temp? Thanks
