Tanks: they leak and they lose temperature. WHY?

[Bob-D659]

If you are doing C41, the dev mixing with an acidic stop or the bleach generated a LOT of CO2 gas, more than enough to pop a sealed lid off a tank.

Even garden variety fixer like Ilford Hypam tends to want to release some gas.

And David, a $20.00 tank is a cheap one indeed!

Try Durst tanks. Mine leaks not a drop but filling and emptying takes a little longer than my Jobos which with vigorous inversion will leak slightly but not enough to make a difference to the safety margin that Jobo builds in when it tells you to use 240 mls for 35mm and I fill to 250 mls becasue it is an easier number

It took me a while to get used to the stainless steel reels and tanks. Now that I am I like them so much better than using plastic because:
1-Now that I have the hang of it, I can load the SS reels faster and more easily than the plastic. I've also never had a steel reel pop open and spring the film loose
2-Since I started processing C-41, the temperature control of the steel is very convenient.
3-They use less chemical (580 ml in the Paterson vs. 440 ml in the SS for 2 35mm rolls)
4-The steel reels and tanks are easier to dry and can still be used without trouble even if not perfectly dry. Not so the plastic.

I have a single real SS tank that does not leak, although the steel cap is sometimes a challenge to get off in time critical spots when changing chemicals.

A Question:
The plastic lid on my double reel SS tank has a crack in it and leaks, does anyone know if these can be replaced?

I use SS Nikor tanks exclusively for 35mm to 4x5 sheets. Tempering bath for C-41 and E-6. Never had a problem with drips, never had trouble maintaining temperature.

Some "problems" are problems only if you want them to be.

even my yankee hand tank that has a crack in the side
from overzealous d-bubbling doesn't leak ...
unicolor drums, well ....

Yes. They should be readily available.

Thanks for that. I didn't think to check, I had assumed you needed to buy everything new. I suppose they all must be a standard size.

I use a SS tank with a flexible plastic lid as originally made by Kindermann. They never leak. The SS tank and a water bath allow very precise temperature control.

I second that, I use the same tank. If it leaks, it's because I didn't make sure the lid was pressed down all the way, which is in no way the fault of the tank.

I use Paterson tanks and actually twirl agitate the bleach and fix steps with the tank sitting in a tempered water bath (in a small Playmate cooler). This has been working well for me.
