Im about ready to throw in the towel with this hobby. I've battled a complete loss due to velvet, digitate hydroids, ALK/CAL crash, high phosphates and now high nitrates. I don't understand it. My nitrates are somewhere between 20-50, I only have a nitrate API kit, so you all know how hard that is to read. My phosphates with the Red Sea kit are less then .16 but more then .08 (somewhere in between the color wheel). I dose NOPX, run ROWA and chemipure elite. I feed twice a day, usually spiralina/mysis and ROE. I also feed nori daily.
