After some more digging on the net, I found a comment from Sandy King on
photo.net that refers directly to my question....
He states "I have more recently conducted tests adding a small amount of
a 1% solution of Benzotriazole directly to the working solution and it
appears that all that is needed is about 1ml of the 1% Benzotriazole
solution per liter of working TEA. At this amount B+f is still very low,
about log 0.07 , Dmax is quite high, and EFS appears to be about what I
would expect with Ilford FP4+."
I think I'll just confirm how many drops from my dropper style will
equate to 1ml and I should have a good start. Sorry for the bandwidth!
