Hi Michael,

When you mixed the sensitizer, did you use distilled water? I had a similar
problem when using tap water. Did you filter it before putting it in the
bottle? Also, I found that if the sensitizer is bottled soon after mixing
the green crystals continue to form. I usually mix the sensitizer and let it
sit overnight in an open beaker in the dark and filter it (through 2 coffe
filters) before putting it in a brown bottle.

Hope this helps, Scott
