Diesel Fuel Additives, biocide, etc

[Biglex]

I have been using startron in my biodiesel fuel mixes, and it seems to work well in cleaning out fungus and algea type crud in the fuel, and also seems to help prevent it as well.

Basically I am just trying to see what other people use, and what type of results they have had. I have a bottle of PRI-D that is supposed to be really good too, so if anyone has tried either of these, or any others and has any info on them, that would be most appreciated.
