PS: I don't mix at 1:1000 like Ralph, but probably half the recommendation, about 1:400. Precision is not critical with this stuff.
I also have precipitates after some 12-15 processing. I am used to lightly shake the solution under the light, just to see or not the precipitates.

Good idea to reduce the dilution. Mine was 1:200 as Kodak recommends.
