We have added 1 to the raw counts and then taken the log. Is it acceptable to add one to the log values?

There is an analytical technique called "zero inflated statistics" which might be useful. Ecologists use it but I'm not sure if it is only applicable to poisson (count) distributions, which may make it necessary to separate your data into divisions as if you were drawing a bar graph.
