Treating Algae in Poly Diesel Fuel Tanks

Poly Diesel Fuel Tanks

Finding out that one of your poly diesel fuel tanks have algae is one thing, but trying to eradicate them for good and keeping them at bay is another ball game. This is the kind of game that you don’t want to be on the losing end if you don’t want to have a perpetual headache.  

Provided that you know what the right solution is, treating algae in diesel fuel is pretty simple to handle. When we say simple, what we exactly mean by this is that you make sure to follow our recommendations below. Doing so will give you better chances of putting this problem behind you.  

Remove Water from Your Poly Diesel Fuel Tanks

When it comes to removing algae and other similar microorganisms from your tank, this is the first in a series of steps that you need to do and follow.  Much like any other organism, fuel microbes need water for them to survive, thrive and flourish. Say that your tank has at least half an inch of water, your best option here is to mechanically drain the water out of it. Should there be anything remaining behind, you can make use of water-absorbing chemical treatment for this purpose. Failing to completely remove water would render your succeeding efforts futile.  

Instead of Generic Water Treatment, Make Use of Biocide

No, we haven’t forgotten that we advised you to make use of a chemical treatment to remove the rest of the water in your fuel tank. It still applies here. But doing that alone won’t exterminate those microbes off. The main purpose of that treatment is to fix the environment and make it harsh for these organisms to thrive and grow in the water.

This is where biocide will come into the picture, it’s purpose mainly is to extinguish the existing active microbial contamination in your tank. Please be aware that fuel biocides are heavily controlled and regulated because they tend to kill any living organism that

I know we just advised to clean up the rest of the water with chemical treatment. That recommendation still applies. But that treatment isn’t intended to kill off the microbes, but rather, to fix the environment to make it harder for them to grow in the water.

Heavily regulated and controlled, fuel biocides tend to kills whatever active living organism not only in water but to whatever liquid they may be used to thrive in, which is a good thing. It will allow you to extinguish mold, bacteria, fungus, and algae. Scavenging the water alone won’t let you achieve the same.

Avoid Undertreating

The common mistake of many when treating algae presence in a poly diesel fuel tank is to undertreat it, by administering only measly amounts of biocide to the affected fuel tank.

When administering biocides, make sure to add enough of it to treat the greatest amount of fuel a tank may be holding and not only the fuel it contains that that particular moment.  

For instance, you have a 12, 000-gallon tank and you have it filled with 5000 gallons of fuel only. The best way to go here is to mix enough biocide to the tank containing 5000 gallons of fuel, this way you are treating the 10,000 gallons.

And by the time they would finally add fuel again, what they will have is 10,000 gallons of fuel with the precise amounts of biocide, powerful enough to exterminate everything it comes in contact with.  

Of course, there are a dozen of other valuable tips that will not be covered here. But by making sure your actions are in line with the recommendations we laid out here, you have better chances of resolving this problem the first time.
