I've been dosing sodium nitrate for a while now. I got tech grade which is 99%+ in purity, 10 lbs bag very cheap. I mix 25 teaspoon in 1 gal ro-di water and dose 50ml daily which keeps nitrates in my 250 gal tank right at 2ppm.
Noticable changes: really good polyp extension on SPS and brighter color compared to when I kept nitrates and phos at absolute 0. Now I run nitrates at 2ppm and phos at 0.01
