Why brine specifically? Would tiny flakes or even reef roids not be adequate??If you want to grow them on a large scale you will need for the Aipatasia:
1. A large shallow container
2. A heater set for 28 to 29 Celsius
3. Activated carbon as substrate
4. Water movement
5. Tank water
6. Brine shrimp incubater
7. Brine shrimp eggs
8. Air pump
9. Water from a cycled tank with frequent water changes from the cycled tank.
set it all up as you would with any other tank, feed live brine shrimp every couple days and cut the Aipatasia in half every 4 to 6 days.
