Before trying it out, it would be a good idea to read the full thread, particularly the safety recommendations concerning Ammonium Thiocyanate--

It's an interesting formula. I don't think I would use it, though, unless I were really developing film in quantity, where a couple of minutes of fix time saved might be more meaningful. TF-4 is fast enough for what I do.

I've been using this fixer with My Rapid Universal developer, and getting fully developed and fixed film in less than 2min. Amazing. Absolutely no odor, and very simple to mix. I've been going from developer, to a quick fill and dump with water, and into the fix, and haven't seen any pinholing in my negatives. Thanks Ron!

I am now up to Super Fix VII.
The goal of this project is to develop a fixer (no pun intended) that is faster fixing film and paper, but also is faster washing and gives better image stability. SFI shown above, does not achieve that goal yet.
SF VII seems to achieve that goal. I hope to release it ASAP.
BTW, the safety recommendations for thiourea are a concern due to reports of carcinogenicity notwithstanding the fact that thiourea is a common chemical produced by a variety of flowering plants. The concerns for thiocyanate are overstated in the thread due to confusion among some between thiocyanate and cyanide. Thiocyanate is present in many photographic processing solutions.
