You used the SP-445 tank for 120 film? I just use a regular dev tank w no issues.

SP445 is for 4X5 sheets. I am using the ARS-Imago lab-box for 35mm and 120.

Actually first try at 35mm today, Delta 100 with continuous agitation. Added a bit of time since the monobath liquid's got a few rolls under its belt. Also, Delta 100 is one of the films needing double processing time in the Df96.

DF96 is meant to have a shelf life of 2 months once opened, and 16+ rolls of film capacity.
I'm now at 2 months and this is the 13th roll. I've also developed roll 14 and 15. Looks ok but the liquid is now murky.
 
You guys are getting good results! I did notice development streaks through the sprocket holes with Foma 100, I think the temp was a little high - perhaps my next Foma 100 roll I will go extra gentle and/or drop the temp a degree or two. I developed for 6 minutes at 72 degrees, which is within the +/-2 degree margin for error. I might try closer to 69 degrees and stick to the minimal agitation.

I had been using the powedered kit and mixing myself, and had probably a three month shelf life no problem, and about twelve rolls before the developer started functioning poorly. I opened a bottle of the premixed (liquid) fom three months ago and unfortunately didn't use it for a while, when I opened it again the other day it was quite exhausted, a dark brown color. Liquid may not last as long as powdered since it has already been mixed whenever it was manufactured.

I got development streaks like that when I didn't agitate the dev tank enough. First when I went with their recommendation of using the twirly rod thing. Then I switched to inverting the tank - the streaks went away when I inverted for 10 secs every minute which is much more than they recommend.
