- Your fuel pH is lower than it should be.
How do you stop algae in diesel fuel?
Diesel algae can be prevented by maintaining water levels in the tank. The use of a water controller will help regulate water buildup in diesel fuel. If algae begins to grow in the fuel tank, drain excess water and treat the fuel with a regulated biocide. Algae in your fuel tank is not a problem that should be ignored.
What does algae need to survive?
Algae only require a few essentials to grow: water, sunlight, carbon, and nutrients like nitrogen and phosphorus. From salt water to fresh water and everything in between, the diversity of algae means that there are suitable strains that can take advantage of nearly any water resource.
Is algae a renewable energy?
Algae are believed to be a good source of renewable energy because of its rapid growth rate and its ability to be cultivated in waste water or waste land. … Algae are the fastest growing plant and theoretically have the potential to produce more oil or biomass per acre when compared to other crops and plants.
