I wonder also if this flow issue factors into the filter size debate that
has gone on here an other places. 2 micron filters would reduce the flow
rate and thus the effectiveness of the water separation. In a situation
where you were just barely getting enough water out of the fuel, passing
some particles on the the secondary filter(s) might be important. Also, if
filters are operating close to maximum flow, they won't be able to hold as
much before needing replacement. Secondary filters, which are not also
called on to separate water, would then be the best place to deal with the
finer particles.

In a situation like mine, where water is an insignificant problem, the
smallest filter I can buy is way oversize for the optimum flow rate, and the
secondary is a real bitch to change out, continuing to run 2 micron elements
in the primary makes sense to me.

What do you think, Joe?

Seems your additive is making the alge smaller, and water particles
smaller, so I'd stick with finer filters. The alge growth is not
effected much by water in the fuel. Your problem is due to fuel
sitting to long in the tank and degrading. Todays diesel is far more
unstable than it was 15-20 years ago due to all the catalytic cracking
to squeeze more out of a barrel of crude.

What we call alge is really tar and wax ect..ect..seperating from the
light oil and forming globs. Best thing you can do is use your fuel up
asap, or install a polishing system.

I'd suggest lots of motor sailing for you.. and a 12 pack of filters.
