Digital BW, The Print

It's been awhile since I mixed this.

My standard practice in mixing is to use my darkroom scale, which I use for
making my own developers.  It reads to .01 grams, and has been accurate
enough for measuring phenidone in developers.

Algae needs light.  Mold doesn't.  I don't know if it is mold, but it seems
unlikely to be algae.  (I run reef aquariums, and so I'm pretty familiar
with algae.)
