Getting way off topic of original post, butt Blix is NO PROBLEM at all for use and discard home development. For use within 4 weeks of mixing, it is still potent and removes all silver. Tetenal E6 kit which uses blix gives results as good as the old Kodak. 7 Bath kit, but is much more convenient and simpler to use.
I base this on several hundred rolls over several years with the Tetenal kit.
Blix is nbe good for a replenishment system like labs use, in which the base chemical stock is used for many months, and slowly topped up or replenished with fresh chems. It is not long term stable and should be used and discarded within 4 weeks.
