Nitrates and Phosphates at 0

[Bear Claw]

My nitrates and phosphates have been stuck at 0 for a long time. I finally have decided to start dosing them as I feel it would benefit some of my soft corals. How should I go about doing this? I was thinking of getting the ESV Nitrate but I am not sure. Thank you!

That product is fine, but so are food grades of sodium or calcium nitrate, or ammonium bicarbonate or chloride. For phosphate, I recommend food grade sodium phosphate.
