 In my 65 Gallon system, each Clam I added reduced my Nitrate by 5-10ppm.  So the 3 Clams I have take care of alot of Nitrate, I run at around 5ppm.
Hey Mike, Sharkbait (Chris) from the WFF has a Sulfer Denitrator that he may be able to rent or lend to you.  He had Nitrates higher than you, and the Denitrator knocked in down in a couple weeks, he doesn't run it now, keeps it just in case.  Still do the DSB, but you won't see the results for quite a while.
