I got a kit from the store yesterday and I’m dying to see them. They’ve also swished around in the tank a little. I hope that’s O.K. 
Thanks A lot!! Also Ten Points for best answer!
About how long will it take for my Triops to hatch?
One Response to About how long will it take for my Triops to hatch?
About 12 to 48 hours.
Be sure to use distilled, deionized, or spring water. Keep the water between about 68 and 78F, and keep a bright light shining until they hatch (you can turn it out at night as long as you keep the water warm). Since you sloshed it around, take a RINSED AND DRIED spoon and wash any eggs that got stuck up on the edges back into the water.
I think that the more pure the water is, the faster they’ll hatch, due to osmotic pressure; if the temperature is low (like 65F), it will take longer also. With most tapwater, nothing will hatch. Remember that water will always be a few degrees cooler than room temperature unless it is heated (by a heater or lamp).
The shortest I’ve had to wait is 18 hours, and the longest is 36 hours. But sometimes larvae keep hatching even a couple days after the majority (after 5 days, for example). Something should hatch within 3 days, or you may have messed up somewhere. They are VERY VERY hard to see at first, though – about the size of an egg, but shaped like a teardrop with wings.
