Would love to see any pictures of the build, especially the underlying structure, as you progress. I am planning a test build of a 12x12x30H tank for some BETFs. Will have to add a front with some vent panels and hinges. Am thinking about a tiered substrate slope(i.e. Vietnam rice hills) with lots of plants. Will look at the recommendations from Viper as well.

Post pics when you can.

Thanks, Caverboy
