Interested in trying live food? This kit includes a soda bottle compatible barbed cap and a mixture of brine shrimp eggs with marine salt. This kit includes enough to make a 2-liter bottle’s worth of baby brine. You supply a pump, airline, and a 2 liter bottle and you’ve got a brine hatchery! This kit can be reused with any brine shrimp eggs out there, but email us if you’re interested in refill kits!
