If the water softener is old and nasty, it may be part of your problem. Seachem also makes a filter medium called Matrix which allows the anaerobic bacteria to colonize it, and is supposed to help with nitrates.
Yep- misquoted. It's normally 10-20 ppm (orange) but the 5 plants I put in last night have already brought the Nitrate down to 5 ppm.
