I just use Ferric Chloride in a plastic food container that has a sealed
lid.

No need for agitators and such.

Just use insulated "bell wire" standoffs on each corner of the board and
place the board copper side down in the etchant. While gravity pulls the
etched copper off the board, go and have a cup of coffee and the board
should be etched by the time you come back. You may need a way of
heating it, but I've never had to worry much at room temp.
