Can Sea Foam help with algae in diesel fuel? [SOLVED]

Thanks for the question Archie!  Sorry, we do not currently offer any products that would help with algae in diesel fuel.  Sea Foam engine products are formulated to clean petroleum residues and engine deposits.  You will need to look for a product that works specifically to eliminate (biocide), prevent or manage algae in diesel fuel.  I would seek a product recommendation from an experienced diesel mechanic or someone that manages a lot of diesel equipment.
