Well, you make a calibration solution, as found here: http://www.reefkeeping.com/issues/2004-06/rhf/index.php

You can't actually fully calibrate a hydrometer, but you can make a note of how far it is off and mark that for future reference.

I put a period at the end of the URL. Should work fine now.
