Introduction, and a question

Hello to all.
As a first post, I´d like to introduce myself. My name is Rodolpho
Pajuaba, I´m an advertising photographer in Brazil, and I like to look
for new things to play in photography as a way to escape from the
pressure. I´ve been printing cyanotypes and Van Dykes for a while now;
at first I used the old formula for cyanotypes, but since I purchased
the new formula I never went back to the old. But, on a few days, I´ll
be making a workshop where I´ll teach these techniques. As I don´t want
to buy more NC for now, I´ll stick to the old one. My question is: Is it
only me, or all of you who´s using this formula encounter problems with
mould? Is there any way to get rid of it? Is it storage-related, or
intrinsec to the chemistry (on the citrate only)? And does this problem
ruins the solution, or it can be used even with that white layer above
:-) ? (I mean, after filtering, of course)
Thanks a lot in advance,
Rodolpho Pajuaba
