wife has decided she wants to start hatching and growing her own brine shrimp for our saltwater tanks. we have a 5gal that they will be going into but need to know how we should go about hatching the eggs. the 5gal will be saltwater so should the water in the hatchery be salty as well? i have air pump, air stones, and tubing, what else should i need? thanks in advance for all your help.
