Sea Monkeys - upgrading tank? - Please HELP!

[SeaMonkey06]

So my sister has some Sea Monkeys (a breed of brine shrimp) and they came in a really small container that we can't even nearly fit the air pump into. We have just purchased a 20L tank to move them across to and I was wondering what kind of salt I should use for the water? And anything else we need to do before?

SEA SALT


And I don't mean table sea salt. I mean a good sea salt mix.

Marine salt, and you might need a refractometer or Hydrometer to measure your salinity, too.
