Algae in Diesel fuel

[dsgsr]

My 275 gal. fuel tank sat for 1.5 yrs. unused. It had about 30 gal. of off rd in it. It got algae and I tried the treatment of Soltron which always took care of it before (when it was used more regularly). It did not work this time so I have drained the tank. What should I use to clean the tank before re-using?

Thank you,
David

Is it something you can clean physically? You know, see in and possibly get tools into etc? How bad is the sludge inside? Just a little or is 1/2 the tank covered in slime?

My first move with the tools I have would be to see what a pressure washer would do. You're going to want to get the sludge out obviously, fuel treatment may kill the algae but the waste product will remain.
