I have a stubborn nitrate problem, stuck at .10 ppm for several weeks. I added a bag of Seachem Purigen a month ago and it has not worked yet. I do a 10-15% water change every 10 days and change my filter sock every three or four days. My tds meter shows my RO/DI water at .001 ppm.
Any other reputable nitrate removal products out there? I don't think I'm disciplined enough to dose Vodka.
