It's years since I had to use trays, but the etchant is so spent that it takes an hour to etch a board.
So quarter fill the sink with hot water, fresh etchant in two trays & 9 pcbs made in an hour and twenty minutes.
The kiddies have drilled them, assembled the components onto them & we tested them, and they all worked (eventually).
