Donna... I could be wrong, and maybe somebody else will step in, but if they sank to the bottom, I would get them out of the water and planted before they get water logged and rot.

Did you try sowing a few to see if they even needed any kind of treatment? I just sprout a bunch of 2007 and 2009 seed right along some 2013 and the older seeds came up faster than the newer seeds without any treatment.
