Hi Jamie - welcome to the forum Ozric has confirmed 12% is good; I understood it should be about 12" off the back of the torts - hopefully someone will be along to confirm that. With your one tort having a visual disability, may well be a bit trial and error for their scenery Have you tried the substrate at different levels with mounds and maybe some largish pebbles/stones that they need to go round as opposed to climb over? Different textures would prob work too, piece of slate, small pebbles they can walk over. If you haven't already you could also perhaps consider some plants - spider plant, aloe vera etc.
