We just received our FedEx shipment of our SeaMonkeys from NiftyCoolToys in Utah. We mixed de-ionized/reverse-osmosis water of zero conductivity heated to 84F for use with the SeaMonkey 1-2-3-4 kit. We are going to try it using just a 100Watt incandescent bulb situated 12inches above the 3 SeaMonkeys sets to see if the hatch times are faster than using our waterbath method.
