I'm getting closer to ordering my chems for the E-6 stuff.

The first developer uses phenidone. Can I just sub metol instead? Adjusting by using 10X the amount of metol instead of the phenidone in the formula?

Can I use Sodium Borohydride in the reversal bath instead of potassium borohydride? If so what sort of adjustment?


edta na 4 is EDTA Tetrasodium?
