What are the formulas for sepia tonig and selineum toning

[Floyd]

I need the bleach formula and whatnot. Can anyone help? all I remember is isn't one of the one to 9?

It varies across brands but yeah, 1-9 is quite a standard dilution. I prefer to work with a weaker solution, like 1-20. It allows me more time to determine the removal point as on many prints (with a dilution of 1-9) it can take a matter of seconds.

Are you trying to mix your own from scratch? Or are you talking about mixing up a packaged brand of toner? 1 to 9 is a common dilution ratio, but I would find the manufacturer's instructions online.

Own from scratch.
