I would go the plastic tub route personally that is what I use, for one you can melt air holes on the sides and keep the lid on without holes, this will keep the humidity up, also It keeps less light from entering than glass obviously, and they spend much time underground in the wild so they don't really like bright light. I use worm bedding for substrate, you can buy it in a box at Walmart $2.00 just follow the directions mix with water, in my oppinion this is the perfect sustrate, it stays moist and stick to them and the eyes as much as other substrates. And it's easy to clean a plastic tub out and change the worm bedding frequently. As far as filtering water with a turtle filter, I wouldnt bother , get a 12" plantic plant pot tray, and put that in the tub with 2" of worm bedding, fill the plant pot tray 1.5" deep with water, and change the water every few days when you feed them ( crickets, nightcrawlers, mealworms, F/T pickies on occation) and then every once in a while you can easily clean out the plastic plant tray with 10% bleach to kill bacteria ect. Also keep them in as cool a spot as possible the like it cool not warm, 60s-70s in the basement works well. Hope this helps.
