Submit a request 2 Comments Date Votes 0 Trevor Bowes April 07, 2017 00:22 i've noticed as I reuse the monobath that the free silver from previously developed films starts to cause almost like a sepia effect. I was wondering if there is any way of stopping this? Has anyone got any suggestions as to how to filter out the accumulating silver content? 0 Sam Hiser April 11, 2017 20:19 Trevor - The free silver in used R5 we call "SLIDGE". It may be decanted out of the solution with a coffee filter; and indeed this can extend the life and usefulness of your bottle of R5. Encourage you to do so. -SH Please sign in to leave a comment.
