Donald, thanks for your 'concern', but I'm not confused. You are simply ignorant of my working practices. Maybe you could have asked before you started talking out of your behind.

The 200 ml of 1.5% HCN solution is in the tray for a total of 20 seconds, then it's back in the plastic storage bottle. And, I know full well that the plate has to be completely rinsed of the acidic developer prior to fixing. hmm-K?
