Hi, The last 2 years I have been very happy with the DS14 paper developer, designed by Ryuji Suzuki. In combination with the replenisher it works like a charm in my Nova tank, with a working live upto 6 months. Yesterday I lifted off the lid of the Nova tank to dicover that a nasty slimy mold/fungus had formed in the developer. It still worked though, but it is not optimal, to say the least... So what compound could I add to the developer to prevent this growth? Obviously the compound shouldn't interfere with the developer characteristics such as pH etc. Thanks in advance! Best, Cor ============================================================================================================To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
