Take a look at lowering your pH. Nitrite/Nitrate formation will be significant above pH 9 s.u.

Hi Brick583, I'm wondering if you're creating chloramines which are then being picked up in the nitrate/nitrite tests? Superchlorination would help. I've attached a link to the wikipedia article about chloramines. Regards, Kevinhttp://en.wikipedia.org/wiki/Chloramine

Here's another idea to consider. We've found peroxide dosing to be effective at higher concentrations. Nix the air stripping idea. It was one I threw out there without thinking. http://www.h2o2.com/industrial/applications.aspx?pid=105&name=Sulfide-Oxidation

Hi griffrob, I agree with bimr. Your calculation of chlorine demand may actually be low because there may be other constituents which may use up chlorine before it gets to the sulfides. Air stripping, manganese greensand filtration and activated carbon are a few other options to consider...
