Bisulfate or Sulfuric for Bichromate Bleach?
Is there any reason to use the one over the other? I'm considering
the Liam Lawless method for makeing enlarged negatives. I think
his process may be the salvation of some thin low contrast
negatives I've waiting.
Patrick Dignan indicates either will work and I see bichromate
formulas which do use the bisulfate. Dan
Even though I use Sulfuric I do think bisulfate will work also.

i've only used sulfuric and it seems to work well...i had trouble locating sulfuric but in the end got it from a car battery shop, battery acid i believe is a concentration of around 35%.
