A few years back, my reading indicated that having some nitrates was no problem but having either too much (hundreds of ppm) or too little (<40ish) could be detrimental.
Frankly, I'd rather have live plants than the contraption I mentioned above. If, however, you're a keeper of fish that won't allow plants to prosper, a "denitrator" may be worth considering if nitrate buildup is what dictates your water change schedule. At least, that was the thinking the last time I was anything near "current" on such things.
