Hiya and welcome, I use sand and soil as substrate on my table, but some people's torts have had trouble with the sand getting into the torts eyes so just use Soil. I have some readigrass in the hide for my tort to did down into to sleep.
You will need a slate to put your torts weeds on to keep the substrate getting onto their dinner and also it will keep your torts beak nice and trim.
A cuttlefish, for extra calcium and also to keep the beak trim.
Some flatish stones for them to climb over to keep their claws nice and short
A water dish with a few pebbles in to enable them to turn back over if the flip over in the water
Do you have any pics of your set-up at the mo, we can maybe give you suggestions on waht you have and what you can get
