[Alt-photo] Salted Paper - Casein salt size

Two questions.

I'm interesting in trying the Casein salt size mentioned in "Salted 
Paper Printing" but have no sodium citrate on hand - just sodium 
chloride.  Can sodium chloride be substituted for sodium citrate in some 
way in this recipe?

And - does changing salting and salt-size formulas require recalibrating 
my times?  I've just used the Universal salting receipe mentioned by 
Marek Matusz to date - so this is the first time I'm branching out with 
other formulas.

Many thanks for the info.
