What You'll Learn
Use a biocide treatment
Biocide treatments are the most common method for eliminating diesel algae. Biocides are chemical agents used to control the proliferation of harmful organisms. They are often poured into the fuel tank to control the growth of microorganisms, such as bacteria and fungi, that contribute to fuel contamination issues.
Biocide treatments are effective in killing microbes in diesel fuel. They can be used as a quick-kill solution and for long-term diesel fuel maintenance. Biocide treatments prevent fuel-filter plugging and help prevent fuel system failures by protecting fuel system components against organic acids created by microbial growth.
However, there are some drawbacks to using biocides. Biocides do not address the root cause of microbial contamination and must be used frequently to prevent future outbreaks. If biocides are introduced into the tank too often, it can lead to the development of biocide-resistant strains of microbes that can survive the treatment. Additionally, biocides are toxic and can harm more than just the diesel algae in the fuel. Over time, repeated use of biocides can corrode the fuel system, leading to costly repairs.
To use a biocide treatment effectively, it is important to follow the instructions on the product and use the recommended dosage for your specific tank size. Some products, such as Bio Kleen Diesel Fuel Biocide, require you to add the biocide directly to the fuel tank to control microbial growth. It is important to note that biocides should not be added to the diesel exhaust fluid tank.

Drain and clean the tank
Diesel fuel is a common choice for powering large vehicles and equipment due to its high energy content and efficiency. However, it is not immune to contamination. Diesel "algae" is a common issue, caused by microbial growth. This sludge-like substance can be detrimental to your diesel tank and engine.
To effectively clean and remove algae from your diesel fuel tank, one of the essential steps is to drain and clean the tank. Here is a detailed guide to help you through the process:
First, you'll need to completely drain the fuel tank. This is a crucial step as it allows you to remove the contaminated fuel and any water present, creating an environment less conducive to algae growth. Make sure to properly dispose of the drained fuel according to local regulations.
Once the tank is empty, inspect it for any signs of algae buildup or residue. Use a bright light to identify areas that require more thorough cleaning. You can use a combination of hot water and soap, or a heavy-duty degreaser, to clean the interior of the tank. A pressure washer can also be used to break up and wash out the algae. If using a pressure washer, aim for a back-and-forth motion to effectively reach all areas of the tank.
For more persistent algae buildup, consider using a steam cleaning service. Some companies offer mobile cleaning vans that can pump out the fuel, perform steam cleaning, and then pump the fuel back into the tank through a fuel filter system. This ensures that not only the tank but also the fuel system is thoroughly cleaned.
After cleaning, it is essential to completely dry the tank before refilling. Leaving the tank to air dry overnight can help ensure that all moisture is removed.
Biocide Treatment:
As an optional but highly recommended step, consider using a biocide treatment. Biocides are chemicals that kill bacteria and other contaminants. After ensuring your tank is clean and dry, add a heavy dose of biocide and move it around a few times daily for several days. This will help prevent the growth of new algae and kill any remaining microbes.
Refill with Fuel:
Finally, you can refill your diesel tank with fresh, high-quality diesel fuel. To prevent future algae growth, consider using fuel additives that remove water and regularly drain water from your water separator.
By following these steps, you can effectively clean and remove algae from your diesel fuel tank, ensuring the optimal performance and longevity of your engine. Remember to always take necessary safety precautions when working with fuel and cleaning chemicals.

Use fuel additives
Diesel fuel is a popular choice for powering large vehicles and equipment due to its high energy content and efficiency. However, it is not immune to contamination. Diesel "algae" is a common contaminant issue that diesel users face. This sludge-like substance is a killer for your diesel tank. It is much more difficult and costly to get rid of diesel algae than it is to prevent it.
One way to prevent and treat diesel algae is to use fuel additives. Fuel additives are designed to remove water from the fuel, which is necessary for algae growth. By eliminating water, fuel additives create an environment that makes it harder for algae to grow. It is recommended to treat your fuel with a diesel additive and frequently drain the water from your water separator.
Biocides are a type of fuel additive that can be used to kill active microbial contamination in the tank. When using biocides, it is important to ensure that you are using enough to treat the maximum amount of fuel in the tank, not just the current fuel level. This ensures that when new fuel is added, the fuel level will rise, and the biocide will kill any dormant microbes living on the tank walls above the fuel line.
Additionally, it is important to test for microbial growth in your fuel at least once a year. ATP testing is recommended as it is fast, accurate, and less prone to false negatives or positives.
While fuel additives can be effective in preventing and treating diesel algae, it is crucial to use them correctly and in the appropriate amounts. Overdoing the additives can create more problems, so it is important to follow the instructions and guidelines provided by the manufacturer.
