I have (in the past) had a small tank set up for keeping Brine Shrimp. You need to keep the water very cool and provide extreme airation.
I used CC with under ground filtration for the Bio/mechanical filtration and had to do weekly water changes. All other filtration attempts seemed to filter out the shrimp
Even with this, the tank only supported the Brine Shrimp for about 6 weeks befor a major tank/gravel cleaning was required.
