Silly question time. How much salt do you add to water for hatching baby brine shrimp. I am currently using 1 1/4 teaspoon to 1 liter of water. within 2 to 4 days the BBS are all dead. I would like to have them live a little longer. I am hatchinh them in a plastic shoe box with 1 inch water, no air. I cant seem to find my hatching cone since I moved. I have both SF Bay eggs and Utah salt lake eggs. Thanks, Jeremy
