Last 4 weeks my nitrates have been undetectable usually they are between .25 and 1. and phosphate has risen from .02 to .08. Whats the easiest way to add NO3? I have a 120 with 75 g sump tank is heavily feed daily I am starting to see some effects on SPS and palys of the nutrient depletion and high phosphate.
