Years ago I used aquarium aerators in FeCl with good results. I suspended
the board over the liquid such that the bubbles/foam washed over the
face of the board. Etched really quickly with nice sharp edges.
When I started with CuCl I purchased an aerator from WalMart
and the CuCl immediately turned it into a pile of sand 8=(.
