I use water for film stop, mix my own citric acid for paper stop.

I use only TF5 mixed with distilled but in separate containers. I don't mix the fix betwixt film and paper.

Up to now I used Rodinal on all film. Ilford PQ for paper.

Most LF film is processed in covered tanks with Gas Burst.

I won't mix any powder inside the DR, I have a shed if that comes up.

Too many dead friends from Industrial Disease at ye olde factory. Not kidding. At least one refused to use the readily available high power vent hoods.
