noticed a brown color to my naphtha found this very odd only thing that changed was the distributor
after about an hour i noticed something starting to form on the bottom of the glass took a drop under the scope - it was plant material causing the nap to apear brown i also noticed that the particles were a bit smaller than what i have seen in the past - my microscope does not have graduations so i am unable to guess the micron size of the particles but they look about 1/3 smaller than from my previous supplier

although they did settle out completely in about 3 hours maby a quick vaccuum filter is in line?

at any rate just thought i'd post this incase it could help someone
