I just picked up the new issue of Tropical Fish Hobbyist and they have a full article on hatching your own brine shrimp; well actually the title is Brine Shrimp Hatching and Metal Toxicity. Here is a run down for you.
Use a 1.5 liter bottle and fill it with salt water from your aquarium (results were faster hatching and healthier nauplii using old water) To the water add 1/8 level teaspoon of brine shrimp eggs and 1/8 level teaspoon of food(brewers yeast, rice bran, baby food powder, powdered fry food...any one of these). Put an air stone in the bottle and leave it on low bubbling slowly(enough to move the water but little enough that the eggs aren't brought above the water line). Leave the bottle in a dim area at room temperature and you will be good to go in 1-2 days to start culturing and feeding your fish. Culture should be good 7-10 days. It is a good article, and I hope it helps you out.

I dont use food. The idea is to feed the BS (to whatever) as soon as they hatch. If you wait hours or days after hatching your loosing nutritional value. Hatch times depend on many variables. I use a salinity / SG between 1.02 - 1.08 ,Iodine free table salt, no heat, 12" strip lite + daylight, and get a good hatch out in 18 hrs.

When raising a hatch for daily use by my dwarf seahorses, here's what I did.
2 cups tank water, 1 cup ro/di. Keep a slow bubbling going and after 24 hours give some plankton for gut loading or feed then if not doing the gut loading. The brine I used wasn't decapsulated, which takes a little longer so I added the phyto and then harvested at 2 days.
As far as the vessel, at first I used 2-2 liter bottles for each vessel. Cut the bottom off of both. Just a little off one and about half the bottle on the other. Take a piece of ridgid airline and put through a hole drilled in the one. Silicone well. Poke a hole in the halv bottle, add sand for weight and feed the tube from the one through the hole in the other one. Easiest way is to just buy one of these:

I started doing this a few weeks ago.
I use about 3 cups of my tank water, air pump (which is not very gentle) and a 60watt bulb about a half inch away from the side of the bottle. I add nothing else 24 hours later Walah! and as said before...feed right away, they lose almost all nutritional value after a day...
