Are the nitrates in your source water? Or solely from the aquarium itself?
Seachem disagrees. Although I've yet to prove them right, they claim that Stability in conjunction with De*Nitrate, Matrix or Pond Matrix will culture the anaerobic bacteria that will oxidize nitrate into nitrogen gas.
As you well know, the average aquarium is way to aerobic for the easy proliferation of anaerobic bacteria. Perhaps to some degree under decor or in deep sand, but not what we'd term typical. The media's macro/micro pores is supposed to create anaerobic regions. I can buy it in theory, but not for the lack of trying, I can't provide any testimony.

+1

Additionally nitrates of 10-20ppm are almost normal and expected in a new planted tank. What I happening is the plants are using ammonia to get nitrogen and forgoing nitrates.

Then as the aerobic bacteria build up and consume the ammonia, the nitrates drop down. Usually tanks 3 weeks or so.

My advice is not to worry about nitrates, don't add anything, and stop doing the water changes.

But that's just my .02

Then I definately recomend against it!!!!!!!

And most especially in a planted tank when ammonia is consumed while consuming carbon dioxide and increasing oxygen.

the exact opposite of growing low oxygen bacteria.

still just my .02

I personally would not waste money on expensive tests you really don't need. I never test for ammonia or nitrite, haven't for years, except when something clearly is wrong (fish sick/dying) I do check water conditions as a first step. But aside from this, once a tank is established, and if proper aquarium husbandry is being done, you will not have issues with the nitrogen cycle.

This may well be, I've no idea. My initial thinking was that bacterial supplements are adding bacteria to quicken the Nitrosomonas and Nitrospira establishment, and the third stage in the nitrification cycle is nitrates, so one might logically assume nitrate would result. Adding further products to deal with this is another step.

So far as I know, stability advertises anaerobic denitrifyers.

Byron; As mentioned previously, my tap water is zero nitrates.

BEALS; I only wish but who needs to test nitrates when they have discus? They show it by their mood and if I don't change water they won't eat. My tank was set up in december.

B; this will only denitrify excess n and not rob plants of nutrients. To the contrary, these are the microbes which work in the rhyzoshere and enhance n uptake.

Seachem Stability:

"The bacteria strains in StabilityŽ have been in development for over a decade. The necessary conditions for growth of our bacterial strains encompass a very broad range. When other bacteria begin to die off (usually from high organic loads caused by the undetected death of an organism), StabilityŽ simply works harder and grows faster! The strains function in fresh or saltwater. StabilityŽ contains both nitrifying and denitrifying bacteria, a blend found in no other product. Additionally, StabilityŽ contains facultative bacterial strains which are able to adapt to either aerobic or anaerobic conditions. The bacteria in StabilityŽ are non-sulfur fixing, another innovation in the industry. Most other bacterial supplements will form toxic hydrogen sulfide under the proper conditions. StabilityŽ will not, ever."

They have likely put some PNSBs in the mix, which can remain in spore form in a bottle for extended periods. I use these bacteria in fermentaions for use on soil. Too bad I'm such a sad case at getting them to establish in my tank.
