Thank you hrst, this firms my belief in Tetenal chemicals. I'll order a new pack when a get some cash.

BTW, what do you pay for a 5L kit in Finland? Maybe it's worth ordering from there. Here in Sweden the Tetenal chems is only available from one dealer (, great service when it comes to analogue stuff) and they charge 859:- SEK for a 5L C41, and 995:- for the E6 kit.
