Nitrate must first be chemically reduced, which costs the algae energy. Several studies link nitrate enrichment, compared with ammonium, to less photosynthetic carbon shared with the coral and greater bleaching under heat stress.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eUrea occurs naturally on reefs and is absorbed fastest under light. Inside the coral, urease, a nickel-based enzyme, breaks it down into ammonium. Use EASY TRACE with NITROUS to supply nickel along with other essential trace elements. \u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eMade with USP- and ACS-grade ammonium chloride and urea. Many reef keepers report better growth, color, and tissue fullness, though results vary with lighting, feeding, and nutrient balance. It is shelf stable for over a year and dosing-pump compatible.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eInstructions:\u003c\/strong\u003e\u003cbr\u003e1 mL per 10 US gal (38 L) daily adds about 0.10 ppm total nitrogen (a safe dose):\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003e0.07 ppm as ammonium (0.085 ppm as NH₃, the form many test kits report)\u003c\/li\u003e\n\u003cli\u003e0.03 ppm as urea\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003eIf fully converted by bacteria, that equals about 0.44 ppm nitrate.

Increase by up to 1 mL per 10 gal each week until nitrate reaches your target. Nitrate may drop at first because ammonium and urea are consumed before they convert. Ammonium uses slightly more alkalinity than nitrate, so monitor alkalinity as you raise the dose.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eCycling (no livestock only):\u003c\/strong\u003e\u003cbr\u003eThe cycling dose is 20× the daily dose and is toxic to fish, corals, and invertebrates.\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eAdd 2 mL per gallon, which gives about 2.0 ppm total nitrogen (about 1.7 ppm ammonia as NH₃).\u003c\/li\u003e\n\u003cli\u003eTest every 1–2 days.
