In this thread PE writes "If the wash is pink or the fix is pink in E6 or C41, this indicates the presence of bleach and thus washing is not complete. The wash after the bleach must NOT be pink. If the stabilzer/final rinse is pink, this is bad!"

Strange thing, though:
The last washes with Sensia/Astia were always absolutely clear.
The same with Provia is pinkish, and Provia turns the Stabiliser slightly pink, too.

Thank you for any suggestion how to improve / intensify washing after the Blix?
