FUJI HUNT Environeg Developer Replenisher C41 Air Control

[foc]

3 An antifungal/antibacterial compound to prevent biological damage to the film later on.

You could try these as a final rinse.

Yes, and that's not really something you'd need in a home darkroom.

An alternative to the 'official' final rinse for a C41 would be a combination of:
1 A dye coupler stabilizer (but this is optional/unnecessary for modern films).
2 A surfactant to reduce the risk of drying spots.
3 An antifungal/antibacterial compound to prevent biological damage to the film later on.

There are many ways to skin these three cats. A simple solution that will work well in a low-volume environment (e.g. home darkroom) is to use demineralized water, add some photoflo (according to the mfgr's instructions) and a few drops of formalin solution. The demi water + photoflo address #2, while the formalin addresses #1 and #3. If you can find something that will address #3 only (and isn't nastier than formalin and doesn't leave residue on the film), you'd be good for modern (post ca. 2000) films, too.

I have everything I need to skin these three cats, but I still want to avoid formalin as much as possible. I'm not sure how big the risks are with such a concentration, but if there is another solution...
The local Fuji distributor does not offer the C-41 stabilizer for some reason.

This is interesting. I've seen these bottles but always thought they were for minilab maintenance. They are available and very cheap.

I also use EnviroNeg chemistry but am struggling with the stabilizer. Can you suggest any solution? I see there's an EnviroPrint one, but I'm guessing it's only for the RA-4 process…

I have two 500 ml bottles of C41/E6 stabilizer concentrate from the old Tetenal Colortec kits doing nothing. Each one makes 2,5 liters.

They are yours for free but you need to pay the shipment from Spain. Detais on PM.

I'm about to run out of my FujiHunt X-Press C-4 developer, but still have bleach and fixer, so I'm thinking I should get FujiHunt Environeg developer replenisher with appropriate starter. Starter comes packed in 6x1L which means that I'll use it up sometime in my next life (as I understand 1L of working solution needs 15ml of starter).

Is there somebody in EU that's in the same situation and would need a starter? Or even better, someone that has excess starter and would like to sell me a bottle?

So, I now have 6L of developer starter. Good enough for 500L of tank/working solution and so should be OK for the next 100 years

If anyone from EU should need a starter and can't get it in reasonable quantities anywhere, feel free to contact me.


Otherwise, I'm curious if anyone is running a replenished regime with their home C-41 processing and their experience with it. It seems the safest bet would be to just mix everything to a working strength and do one-shot processing. But since I process in Jobo tanks, to get the best economy, I have to wait until I have at least 2 rolls ready for processing. With replenished regime I could process single roll (or even a single sheet) of film and just add needed amount of replenisher to working solution. But, replenished systems and recommended replenishing amounts are definitely not designed on the typical home environment where you have a very small "tank" (like 1L of working solution). I'd think that it's more geared to tanks of 10L and more. I'm afraid I'd pretty quickly go out of specs and I have no ways to monitor my working solution (control strips or even pH meter; well, I do index scan every roll with exactly the same setting preset (for every film type) so I could see if index scans would start to get progressively different).

Though, I did run my last 5L of developer in a "self replenishing" fashion (1L of working solution that I replenished with adding fresh tank solution (125ml per roll) to my working solution) and I haven't noticed any problems. So, maybe I should just mix a tank solution and continue with self-replenishing.

Thoughts?
