: non leaky tank??? for color!
: astrobeck January 28, 2022, 09:12:28 PM
Hi all,
I've been going to ask this question forever and keep forgetting until a day like today happens.
I develop color and the blix sneaks out of the developing tank.

I just mixed up a nice new Cinestill kit and developed the first roll no problem...except the red/dracula blood red blix leaks out of it no matter how much I try to seal it.
what's the trick?
I've doing 35mm and hardly ever 120 color.
I'm going to run out of blix before my third roll at this rate.
Thanks!

Is it because the pressure builds-up in the tank and then the lid starts leaking?
In that case just venting the tank from time to time should fix it.

hmmmm.
It's possible I reckon. I'm using a Patterson tank that doesn't leak when I use it for B/W....ever.
Maybe I should just use the metal wire reel one?

I find the Paterson tanks are the most leak proof if you burp the lid.  I prefer to use stainless steel tanks with stainless steel lids but they seem to leak the most.  The plastic lids seal better on stainless steel tanks but I have had a few of them that eventually cracked.  I wrap the stainless steel lid shut with electrical tape but the liquid still seems to find its way out even with three full wraps with the tape.

Yup, burp the lid often, especially with freshly mixed chems. Older blix isn't as volatile.

Or just leave the lid off and use the twiddle stick... Something to do under the stove hood exhaust fan...😐

I always found my tank leaks all over the place if i invert it during colour processing, but is absolutely fine with black and white chemistry, so to save a horrible mess I just use the stick to rotate the spiral back and forth instead of inversion when I'm doing colour.

I have the impression that it's the high temperature at which you develop colour. I have the same problem with my Paterson tanks. I suspect that the lid simply expands more than the rest of the tank. With the Tetenal C-41 kit I was able to develop at 25 °C and there's as little leakage as when I developed B&W.

  I'm with everyone one here concerning the mixture temp. I use the Patterson tanks too and find
that after my first inversion I simply crack the lid and lightly compress the top at the same time and
reseal the edge of the lid . Works every-time .  Peter

I wonder if the Jobo tanks wouldn't be less leaky?
They are made to be used on their sides...
