Wondering what everyone does for nitrate removal. My ammonia, trites, and phosphates stay at 0. My cal, alk, and mag stay in desirable ranges. My nitrates typically stay between 20-30ppm. I tried vodka dosing and got them down, but my LPS started going downhill once the trates hit 10ppm. I don't really have room over the sump for a scrubber. I might could force one in. I am considering a reactor with some media. I just need something that doesn't require phos as well as nitrate to work. Suggestions?
