Yes, I know what "cide" means. I deal with herbicides, biocides, and other types of "cides" on a regular basis. Farmers are not the only people in the world who know about such thing, y'know!
From my reading, I have come to understand one thing about algae growth in diesel fuel: No water in the fuel, no algae will grow.
The algae grows only at the water/fuel interface.
I check my water/fuel separator and fuel filter frequently. No water, no "red algae", so no problem, no need for a biocide.
Again, find and READ the MSDS for the products you buy. It can be very enlightening!

So tell us, what about the fuel in your tank pre seperator. pre filter?

You fill your tank at say 60 degrees from a filling station, Park the truck and the temp drops to say 30. You have an immediate dew point issue and the inside of the tank (above the fuel level) sweats and don't tell me you fill it entirely full because you cannot, physically impossible.

You make internal condesation in the tank (also know as water) and... underground storage tanks (at fuel stops and filling stations also sweat internally so you could be pulling water when you fuel as well.

I have a 1000 gallon diesel bulk storage tank on the farm and at least every 6 months I drain off the accumulated water and it matters little if the tank is clear full (I can fill it to no air space because it's top fill and round) or 1/2 full, it always makes some water.

Your premise don't hold 'water' with me, but when you grow the red stinky, slimy stuff, you'll be in for a real treat. I know, been there, done that and paid the price. I use a biocide regularly, in my truck and in my bulk tank as well.


Not going to spar with you on it, don't really care actually. It's your ship and you Captain it but when your ship engine gunks up, you can deal with it and it ain't a cheap date.
