ah ha! I am currently hatching brine shrimp as I type. I use a small soda bottle, I don't remember what volume it is, but it's 1 step down from a 2lr...a water bottle works well too. A 2 lr is just way overkill unless you have a massive breeding operation.
1)select a bottle and clean it, remove the labeling if you want
2)cut off the BOTTOM of the bottle
3)screw on the cap tightly and place the bottle upside down into a cup so that it fits snuggly (the cup just keeps it standing, otherwise the bottle would be balanced on its cap)
4)fill with tepid water, my bottle takes about 5 cups of water, add dechlor if you want, it's not wholly necessary, I've read that buffering with baking soda can help as well, but I don't do it
5)I then add 3tsp...TEASPOONS...of salt, uniodized is best, but I find it'll work even with iodized, these guys are tough
6)connect your airline tubing to your pump and place the outlet of the tubing into the bottom of your container, it should be as close to your cap as possible so no eggs get stuck anywhere
7)add eggs, be careful. A little goes a LOOOONG way. I bought a 1lb container of eggs a few years back...I will never use all of these
8)place mixture under a light, a desk lamp works well
9)SECURE YOUR CUP. My cat has knocked over 2 or three of my brine shrimp batches...it's a mess. Place somethign heavy around the cup, I use dumbells
10)twiddle thumbs for 15 hours
Harvest time!
1)remove airline tubing
2)allow a few minutes for the water to settle
3)see the pinkish wiggly things? those are brine shrimp
4)take a turkey baster and suck up an area where they are concentrated, usually around the top
5)Squirt directly into fry tank
6)enjoy the carnage
7)put the tubing back into the container
With very yound fry, you can get by for a couple days before the BBS start to outgrow their mouths. When the fry get bigger, your batch of BBS can last 4 days or so before they begin to go bad. Make sure you keep your unused eggs in a cool dry place in a sealed container...I keep mine in the fridge.
