Cloudy diesel

We just pumped a little diesel off the bottom corner of our tanks, as shown in photo
It is cloudier than I expected.
No water separated out, but a few particles like fine sawdust are visible.
One tank was empty and wiped clean last fall before filling.
The other was equally clean a year before that.
What does this mean?
Algae ? anything at all?
We are in Scotland, where boat diesel I dyed red. Fuel has been in tanks for about 8 months, unused
