Going to give SeaWorld a little competition there are you?
What kind of sharks we talking about? 1,617g isn't much space for sharks.
Since money isn't an object (if you want to keep 1,617g of saltwater in tune it must not be), you need to go with an oval or round tank as square tanks are a waste of space and the sharks tend to beat themselves up to much in them.
Sand or bead filtration and depending on the bio-load, on the order of 20x per hour and possibly several foam fractionators. And a backup system.
At least 500g of premixed water for incidentals will also need to be kept on hand too.
