   Please do not expect too much, since this will worsen
   for example the water - ion and solute - ion
   direct interactions (these are already underestimated).
   Nevertheless, in your case you need to get rid of the
   pairs by any available mean.
   I would be very interested to see the outcome.

   Interestingly, we did some NaCl simulations before for
   G-DNA with no visible problem. KCl was not successfull.

   Best wishes, Jiri
