Paul,

Were you using the sandpaper with the fish in the tank?

I had no problems using the the sandpaper in the tank, didnt harm the
fish 
any I could see.

The 2000 grit would be about the finest I would use, beyond that its
similar 
to rubbing with a cloth and polish.  The finer papers also clog up
quickly 
and lose their "bite".
