I've been struggling a little with my nitrates. They've been between 20-40 ppm. Phosphates were as high as .26 two months ago, now they are down around .04 (ish). I would like the nitrates to between 5-10 consistently. I do dose NOPX already. My question is, do I go for the nitrate reactor or recently someone said I could use biopellets in a GFO reactors instead. Opinions?
