2011, Day 237 - Gritty shoreline

Yesterday I was cleaning the filter for my aquarium and because it it is a bulky contraption I put the components in an old enamel wash basin.  Apparently I forgot to clean out the basin when I finished and the debris that leaked out pooled on the ancient scratched enamel and left a ring of grime.  Yes, it is kind of gross because much of this is probably fish excrement but the effect is nice nonetheless...
