What is diesel fuel algae?

Diesel contamination takes on many names: Algae, Bacteria, Fungi Growth, Diesel Bugs, Slim, and Microbial Growth. Microbes (algae) grow at the interface between naturally occurring water in a fuel tank and the fuel itself. Simply put, the oxygen in the naturally occurring wateris the main culprit for algae growth in fuel tanks. Normal tank temperature cycles create water condensation on the inside walls of the fuel tank and that condensation settles at the bottom of the tank due to water being heavier than fuel. Keeping water out of your tank is preventative against microbial growth.
