I'd sump that thing and put plants in it that will eat the nitrates first! Not have to deal with it ..... I have all of my big tanks sumped\planted and may clean the glass once a week, and that's just because I'm picky!
14 Burundi and 6 Goldhead Comps in a 120 that are about to be moved to my 180 and 18 F1 Gibberosa "Lupota's" and 9 F1 Inkfin Calvus that are growing out in a 55 that will be moved to the 120 shortly. Also a couple of tanks of Peacocks....
