A 9 inch turtle will need at least a 90 gallon aquarium/stock tank. You will need a good filter (canister), a basking area where he can haul completely out of the water to dry all parts of his shell, a water heater, a heat light (regular household bulb) and a UVB light that emits 7-10% UVB rays and don't forget that RES love to swim, so as much water as you can fill it up without the turtle escaping. Also plants (real or fake) are a good addition to the set-up but not gravel or rocks smaller than the turtles head. He may eat these and become impacted. Usually either river rock or nothing at all is used for the substrate.
To get specific ideas on the setup you should browse through the gallery section of the forum for pics. Just ask if you have specific questions.
