While the 280 may work for a couple of years for keeping them as pups. By the time the Brown Bandeds get to about 3 years old they will need a larger tank/pond.
Ultimately for two Brown bandeds - I would suggest a pond that's at least 600-750 gallons (either 7.5' diameter or 10'x5' footprint). Keep in mind this species gets to about 40" long.
