Everything I've read suggests it's a 100% replacement -- even to being usable in self-replenishment at the same rate. We'll expect to hear from you after you try it, of course...
My routine is to mix the 5L batches to 1 gallon and both seemed to go into solution equally, too.
Just to understand -- you're running your Xtol/Eco Pro at 25%+ above standard strength? Replenished/stock or diluted?
I place the dry ingredients in a 1 gallon glass thumb jug, fill to the 1 gallon mark with warm water and roll the jug back and forth. It leaves little chance for aeration and avoids the cavitation of my magnetic stirring rig (so much volume requires pretty aggressive magnet action). It all goes into solution and I decant to smaller glass containers. Originally, I tried it to see if it would work, back in the era of "sudden failure" issues, thinking that a higher concentration stock would perhaps be more stable. It turned out to be a handier prep for me and worked well in practice so I just settled into the habit. I keep a small copy of the attached grid posted in the darkroom and it's quite easy to mix the adjusted ratios for the dilution I'm after.
Neat. I am not that worried about sudden death or excessive aeration, but a gallon is much easier to store than 5L. Since I'm replenishing, I realized that I simply cannot use up all 5L of replenisher quickly enough. What I started doing is only keeping 3L and discarding the rest right after mixing. It's cheap and environmentally friendly enough to do this. 3L is good for three months, and I like having a fresh batch every three months.
Including our two sales taxes totalling to 12%, they cost me $16.52 CDN a package - not bad for ~ 70 rolls.
Vellll... we haven't finished doing our developing testing of our first batch of Xtol yet, but once we do, we would like to understand the replenishing part of it, in case we decide to continue with Xtol, So could someone please direct me to a source of information for this.
Another question can you also do the same with eco pro legacy?
Thanks p.

While the developer is still in the tank add 70 ml stock XTOL per roll of 120 film or 135-36 to the developer then return the developer in the tank to the replenished bottle until the bottle over flows and discard the remained. Seal off the replenished bottle to keep out the air.
Same result, easier logistics.
I'm sensing a misunderstanding here... What you've described sounds much more complicated than SG's approach. Why not just add 70ml straight to the working bottle while your film is cooking in the tank?
It is far simpler to add recently used working solution to bring the contents up to the cap, and then discard the rest.I could, I suppose, add enough replenisher to bring the contents up to the cap,
What ya all use for stop with Eco-pro? Water?

You should expect the amount that ends up being discarded to vary slightly each time, due to absorption and, if you pre-rinse, dilution.
The thing to standardize is the air space.

I use a slightly modified version of this for my main paper developer (different restrainer) but haven't thought to give it a shot on film..... I've read of people using it in that manner and perhaps it was from posts of yours. I'm in the midst of a bunch of equipment & lens checks where subtleties of developers won't matter much so I should give it a try.
