To house a great white you'd need more than 50,000 gallons, try 1 million+, you'll need a pretty damn big siphon to clean that tank. I don't think it has been done with much success anyways. http://www.msnbc.msn.com/id/7351538/ If you have the resources and the knowlege to keep a great white alive for longer than the world record of 198 days (no offense, well, maybe a little), I'll eat my hat, your hat, your father's, and your mom's.
