I got this little jewel from Brine Shrimp Direct out of Utah. It requires no aeration, light or heat. It came with a jar of 1.75 ounces 80 percent hatch rate eggs. My fish room is cold so I set it on a 3 watt plant seedling heat mat. One quart of water mixed with 5 teaspoons Mortons Pickling & Canning Salt and one scoop of eggs (handy little scooper also included) gives me BBS for three days. More than enough for my needs. If I start it up at 9 AM, I will have BBS first thing the next morning. $40 bucks but well worth it. I have never seen an easier way to hatch out brine shrimp.
