Yeah, it curls my nostrils just like Glacial, a matter of fact anything above 28% is an intense olfactory injury for me

What its specific constituents are I do not know, but its potency is roughly 90% of the glacial. It is VERY strong. - David Lyga
I'm with you David. I always dilute Indicator Stop Bath just like I would Glacial with no problems (no "pin" holes) for over 50 years. I am careful not to "sniff" my stop bath, and I don't use it in salad dressings, just like I don't "taste" my developers or fixers. I have seen that done.......Regards!I find that its potency is roughly 90% of the glacial. What its specific constituents are I do not know, but its potency is roughly 90% of the glacial.

I always use indicator stop bath - acetic acid based for film, citric acid based for paper.
The acetic acid based Kodak stop works out to be cheaper, but the Ilford citric acid based stop smells better.
Water my entire life, thousands of sheets and rolls. Never had problems that I could attribute. It’s doesn’t “stop” development, it dilutes the developer away so that development stops. I can’t see how that could cause the problems you describe if your agitation is adequate.
That said, water varies, temps can vary, film can vary, and the universe is full of surprises. Taxes, war, sudden audits, and this.
Probably a waste of your fixer too. Especially with T-grain films fixer becomes exhausted pretty soon, this will be worse if you don’t stop the developer in the emulsion.I only use stop when printing. I have found it to be a waste of time when developing film.

it has nothing to do with expense, it has to do with having another chemical in the darkroom to deal with .."Oh, I never use stop bath because it is so damned expensive. I would rather kill my hypo!"

dispose of, mix, breathe the fumes of .. fixer is cheep
The indicator in the Ilford product is conveniently useful, even if it isn't strictly necessary.What advantages does the Ilford citric acid stop bath have over using one tsb of citric acid in a litre of water?

So that's actually an interesting question: If my workflow includes stop bath then I've built in a few precious? seconds of development while the stop bath slows and stops development. If I went to a developer->fix solution, do I lose any appreciable density in my negatives?Haven't used a stop bath in 50 years. Don't have the space on my worktop for another dish, firstly. Secondly, fixer stops development even better than a stop bath. OK, so I may exhaust my fixer more quickly, but it doesn't cost the earth, and I always check clearing time to ensure that fixing time is at least twice clearing time. Result: happy snapper.

It isn't a question of complication. It is a question of passion for process control. If you aren't that picky about your process then I guess the question of stop bath vs water+fixer or just fixer isn't that interesting to you.I cannot believe there have been 128,000+ views and 570 posts on a topic as mundane as whether or not to use stop bath. Photography just isn’t that complicated.

regardless, I was taught to use a stop bath for consistency by the best printers in the world and see no reason to deviate.also PE's reasoning makes sense to me.I was being sarcastic.
If you are picky about your process, you use stop bath; if you aren’t, you don’t. The only question is do you want to stop development uniformly at a certain time or not. Precision or sloppiness, your choice. But it isn't essential; it just eliminates a variable. And it doesn’t require a four month debate. Is this what film proponents have come to? Endless debates about stop bath? Or the ongoing month long debate: Strap or no strap? I guess you are really in your element here. Like a bunch of old geezers gathering at the donut shop every morning for coffee to talk about the good old days of APUG. It's suicidal.It isn't a question of complication.
