I would sell it and buy again later. If you dry it out you're not any further ahead as the rock isn't live anymore. It takes a long time to leech all the dead stuff out of the rocks when you get them wet again, and takes even longer to re-establish the anaerobic bacteria needed for denitrification (different than the aerobic bacteria needed for nitrification that colonize quickly). Besides, the rock is worth something while it is still live...probably $4/lb. Once you dry it out its value is only about $1.50/lb which is easily replaceable, so I say sell it while it still has some value.
