I've been dosing ME coral nitrate for a little over a week. I add 2.5 ml to my 13.5 Evo, which will raise 1ppm. I've been checking it on an API test(I know.. it's what's available to me lol) and it's consistently been reading >5pmm. I've upped the dosage to 2.5 ml 2x a day to raise 2ppm daily. Still >5ppm. I have a LR Hanna checker on the way, but until then, how much NO3 can I safely dose in a day? Aiming for at least 5ppm
