Stop bath is easy to make. It may be perhaps the easiest photo processing chemical to make with home-found ingredients. Next to water of course. Kitchen or table vinegar (plain, none of the types with herbs or spices added) added 1 part to 4 parts water will make an excellent, reuseable stop bath.
I second Fotch in using stopbath. Quickly and positively arresting development (by neutralisation) is better than just slowing it down or weakening it by just rinsing the developer-laden film with water. No worries of getting more development after the film has left the developer. And the fixer lives longer too.
Last night I developed three 120 roll films together. Usually I only do two at the most. So.... when I come to put the stop in, it eventually dawns on me that my ready mixed 1 litre of stop won't cover the films. Duh! So I used water instead. After very careful comparison of these films against ones where I did use a stop - I can detect no different at all...
The films were Delta 400 in dilute Rodinal, it takes a while. Maybe with a film / developer combination that develops very quickly it might have been different.

You could have added water to the stop bath solution to increase its volume enough to cover the rolls you developed. It appears that the exact concentration is not too critical. The usual stopbath contains about 25 to 30ml acetic acid per litre. The concentration will be lowered if more water is added, but nonetheless the solution will still be acidic enough to neutralise the developer carry over.
I use my stop at half the recommended dilution for film. This is not being cheap, rather a means of arresting development quickly, and at the same time, attempting to avoid pinholes or other supposed reactions and imperfections attributed to stop bath.I also give a single rinse between stop and fix, to lessen contamination of my fixer(TF-4). The use of stop for printing does have proven benefits,( unless using a running water bath in place of stop) as the water in a tray becomes laden with developer and turns into a weak developer itself, and carries over to the fixer tray. IMO, this could be more of a problem with FB paper than with RC, but still a problem none the less.
If I were using a rented DR, I would definitly supply my own chems, pre-mixed (as much as feasable)and shun their supplied chems.
I hate that phrase. Bad is an adjective - you can't own it. :rolleyes::o
There, I used them!
Steve, I could not agree more. Why would anyone deliberately use poor grammar and risk being compared with Sarah Palin, who recently used the word "refudiate," an apparent combination of repudiate and refute. She then defended herself by saying that Shakespeare liked to make up words also.
