I don't know all your tank parameters, but going by your OP, were you stated that you reduced light intensity (raised lights) and reduced photo period (to 8 hrs) lends itself to believe that you were running too much light for too long a period in a slow growing tank and the tank just didn't have the bio-filter to deal with it. I doubt this has anything to do with your nitrates. Why do nitrates cure BGA anyway? Since your in a reactive mode I would do the erythromycin has others have suggested.
