Storing X-tol

Hey thanks!

50 ml is 20 ml less than Kodak recommends, so you might get better results if you increased the amount.

Maybe that's the problem. Do you use replenished XTOL too? I'll increase it to 70ml per roll.

I am using replenished HC-110, and will continue to do so until my last supply of the now discontinued replenisher is used up (sigh).

I'll transition to X-Tol (or possibly T-Max RS) then.

The Kodak instructions for calculating the amount of HC-110 replenisher are incredibly complex, as they vary with the dilution used in the working solution. The simplicity of X-Tol or T-Max RS replenished is enviable.

Some people use more than 70ml for X-Tol. I expect that it probably only hurts economy if you slightly over-replenish.

I like look of replenished XTOL

It's pretty simple if you don't under replenish

But I don't think you can over replenish since your using working strength developer right?

Well ...

One of the goals when using a replenishment regime is to reach an equilibrium that ensures consistency.

One of the things you are doing when you add replenisher is removing the same amount of used developer, including the byproducts of development.

Those byproducts are what causes the developer to "season" and are what gives the working solution in a replenishment regime its particular character.

The goal is to reach an equilibrium, so as to ensure that the amount of the byproducts in the working solution remains at or close to the ideal amount.

The danger is that if you increase the amount of replenisher that you add by too much, when you remove that same amount of used developer you may end up removing too much of the development byproducts, resulting in a working solution that "wanders".

It is, however, undoubtedly easier to get at least close to true consistency with a developer that is its own replenisher.

I have stored xtol for well over a year in wine bladders, including the clear kind. The old silvery looking bladders seem to be obsolete. I really like doing it this way. ..zero headspace, flexibility to draw any amount.

I didn't know that

I don't know too much about replenishment though I used replenished developer. But does your technique keep the bromide levels consistent? My technique is always to remove the same amount I replenish since I put replenisher in the working solution first then top off the jug with used developer. I like doing that because I eliminate air in the jug that way.

My technique is your technique.

It is just that if you vary the amount of replenisher you add - increase from 50 ml to 70 ml as an example - you also vary the amount of used developer you remove by the same amount.

And that, in turn, changes the amount of byproducts you remove, including those bromides.

In a perfect world, we would be adding just the right amount of fresh chemicals in order to keep the activity constant, as well as removing just the right amount of developer byproducts such as bromides in order to keep the restraining action of those byproducts constant.

When your developer and your replenisher are the same, it is quite likely that changing how much you replenish may have more effect on the restrainers than the developer activity itself.

That's a useful comment. If as you say most if not all winebag makers are moving to the clear kind of bags then such evidence as this is very useful.

Thanks

Dead Link Removed

I have not tried these yet but my local homebrew store is going to order me some along with the plastic reusable "box" they sell to hold them. These look like an improvement over the wine bags I have been using because the spouts seem easier to remove, and the wine boxes break down and get soggy after a couple refills.

With the latest batch of XTOL I've been replenishing for the past few months or so, I've noticed a gray precipitate that collects in the bottom of the bottle (I'm using glass Absolut vodka bottles). Disturbed by this, I've been filtering it out, only to have it recollect. Is there a way to prevent this? I don't recall having this issue before.

I found some bags here,

but it say it has to be used once.

pentaxuser · Jul 27, 2015

If these are genuine winebags and they look to be genuine then my experience is that they can be used several times.

I'd just buy the bags with wine and drink it
