Well it looks like my Pyrocat HD has gone south on me. I shot two sheets of film and developed one in Pyrocat and the other in fresh D76. The Pyrocat neg was thinner than thin....barely there. The D76 neg was normal.

The only thing I can think of is that my Pyrocat must have gotten contaminated somehow. So I dumped what was left of it (maybe 30 mls of each solution)

Anyway I would like to order more from Photog Formulary or Artcraft. I am wondering however just how economical the kit for Photog Form is. Am I better off to buy the chemicals in bulk? I would like to get enough for 20 or 30 litres of working solution. What quantities of the chem's should I get if I go bulk?

Thanks
