The SDS does not list the pH-sensitive dye which suggests it is considered non-toxic(ish) by Her Majesty's Inspector of Things-That-Can-Kill-You-Without-You-Realising.


(It's been a tiring few weeks ...)
That explains things Bob.

I have started retaining my dilute Stop Bath from printing sessions, in the name of economy and the environment, for up to 5 print sessions.

I have not found any "freinds" growing in the solution, even through I may store it for perhaps up to 2 weeks in total.

I used to dump my stop bath at the end of each session because even concentrated citric stop bath in the bottle used to need filtering because of growths.
