1/2 pound of the highest quality brine shrimp egg and salt mix on the market. It is what I use in my hatchery. The eggs are 90%+ hatch rate. The salt is artificial sea salt with all of the necessary buffers and trace elements required to achieve the best possible hatch and keep the brine shrimp alive after they have hatch. 

Buy more and save! Purchase two or more at the same time and save 10% as well as receiving a discounted combined shipping rate.  Extra egg/salt mix can be stored in the freezer for years.
