Full-Spectrum Nitrogen Supplement - Ammonium + Urea

NITROUS supplies nitrogen as ammonium and urea, the forms corals and their zooxanthellae use most easily. For corals to use nitrate they have to chemically convert it to ammonium which is an energetically costly process. Studies show corals directly fed ammonium get more energy from their zooxanthellae while corals fed nitrate get less energy. During heat stress, nitrate-fed corals bleached worse than controls, while ammonium-fed corals did not bleach. NITROUS cuts out the middle man of nitrate conversion supplying your corals directly with ready to use nitrogen for growth and color. 

Urea occurs naturally on reefs and is absorbed fastest under light. Inside the coral, urease, a nickel-based enzyme, breaks urea down into ammonium. Studies show supplementing corals with both urea and nickel leads to an increase in growth. Use EASY TRACE with NITROUS to supply nickel along with other essential trace elements your corals need. 

Made with USP- and ACS-grade ammonium chloride and urea. Shelf stable for over a year and dosing-pump compatible.

Instructions:
Begin with 1 mL per 10 US gal (38 L) daily. This adds about 0.10 ppm total nitrogen (a safe dose):

• 0.07 ppm as ammonium (0.085 ppm as NH₃, the form many test kits report)
• 0.03 ppm as urea

If fully converted by bacteria, that equals about 0.44 ppm nitrate. You'll see less, because corals, algae, and bacteria use much of the nitrogen first.

For doses above 1 mL per 10 gal, use a dosing pump and dose only during the photoperiod, when corals consume ammonium and urea fastest, so ammonia doesn't build up overnight. A dosing pump with a stepper motor is best.

Switching from nitrate:

Start at 1 mL per 10 gal. 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.

Cycling (no livestock only):
The cycling dose is 20× the daily dose and is toxic to fish, corals, and invertebrates.

1. Add 2 mL per gallon, which gives about 2.0 ppm total nitrogen (about 1.7 ppm ammonia as NH₃).
2. Test every 1–2 days. When ammonia falls below about 0.5 ppm, dose again.
3. The cycle is complete when a full dose clears to zero ammonia and nitrite within 24 hours.
4. Do a water change if needed to lower nitrate before adding livestock.

Ingredients (mg/mL):

Ammonium chloride (10), Urea (2.5), Stabilizers, Water. Total nitrogen: 3.8 mg N/mL.

15 Elements In One Bottle

EASY TRACE delivers iron, manganese and iodine, the trace elements reef tanks deplete fastest, at daily replacement levels. It also supplies low levels of zinc, selenium, molybdenum, nickel, cobalt, vanadium, chromium, rubidium, boron, potassium, sulfur and bromine.

EASY TRACE is designed for steady, low-level input rather than chasing ICP set points. Each small daily dose is sized to be taken up between doses in a typical reef, so levels stay safe without constant testing. Perfect for nano tanks, budget tanks and systems built around simplicity.

Iron in an organic form:
Iron is one of the trace elements corals’ zooxanthellae depend on most, but it’s also the most reactive when dosed as a simple salt. In seawater, bare iron quickly binds to other compounds and drops out of solution, often before corals can use it. In the ocean, nearly all dissolved iron is carried by natural organic compounds called chelators, which protect it from these reactions. EASY TRACE follows the same principle, supplying iron as a biodegradable chelate in a stabilized solution rather than as a bare salt.

Gentle, biodegradable carriers, no EDTA:
Many iron supplements use a synthetic chelator called EDTA to keep iron dissolved. EDTA does solve the problem of iron falling out of the water, but it creates a new one: it grips iron so tightly that it may not let go when your corals need it. The iron stays in the water and shows up on tests, but much of it is locked away where the algae in your corals can’t easily reach it. EDTA is also very slow to break down, so with regular dosing it can build up in your tank over time. And because it doesn’t only bind iron, it can tie up other important trace elements as well.

EASY TRACE takes a different approach. It uses weaker, biodegradable organic carriers that keep iron soluble and stable in the bottle and deliver it in a form that releases easily once dosed. Research on marine phytoplankton has found that iron held by weaker carriers is released and taken up more readily than iron bound to EDTA. Because these carriers are biodegradable, they’re broken down naturally instead of accumulating.

ACS/USP-grade active ingredients for highest quality. Dosing pump compatible.

EASY TRACE provides consistent input of:

• Iron
• Manganese
• Iodine
• Selenium
• Potassium
• Zinc
• Boron
• Bromine
• Sulfur
• Molybdenum
• Nickel
• Vanadium
• Rubidium
• Chromium
• Cobalt

Instructions:
Dose 1 mL per 10 US gallons (38 L) daily.

New or lightly stocked tanks (mostly fish, few corals, or under 6 months old): start at 1 mL per 20 US gallons (76 L) daily and work up as the tank fills in.

Do not increase beyond 1 mL per 10 gallons without testing. Run an ICP after 4 weeks and check iron and manganese. If both are mid-range or lower, increase by 50% (1.5 mL per 10 gallons daily). If either is near the top of its range, hold or reduce. Retest before increasing again.

Reduce or pause if you are battling dinoflagellates or cyanobacteria.

Testing note: Sample for ICP immediately before your next EASY TRACE dose, never shortly after dosing. Sampling within a few hours of a dose shows a temporary spike that doesn’t reflect your tank’s actual levels.

Coconut-Shell Activated Carbon + Macroporous Organic-Scavenger Resin

REDUCE DOC/ORGANICS combines a premium low-dust, steam-activated coconut-shell carbon with a macroporous acrylic anion resin engineered specifically to scavenge dissolved organic matter.

No single filter media captures every organic compound in a reef aquarium. Coconut-shell carbon has an extremely fine pore structure that is excellent at trapping smaller organic molecules, but many larger organics are simply too big to reach most of its surface. Organic-scavenger resin fills that gap: its large open pores and charged surface capture bigger, negatively charged organics, including the humic-type compounds that tint aquarium water yellow. Together, the two media remove a broader range of dissolved organics than carbon alone.

The carbon removes odor-causing compounds, pesticides, herbicides, and many medications and dyes after treatment. It is also commonly used to help reduce chemical compounds released by corals and nuisance organisms.

The resin targets the color-causing organics that yellow water and absorb the UV and blue light corals rely on. Clearer water lets more of your lighting reach your corals.

Keeping dissolved organics under control is a cornerstone of stable reef water quality, and REDUCE DOC/ORGANICS works best alongside protein skimming and other export methods. 

Instructions:

Use the online calculator below to calculate your dosage. Rinse the media in RODI water before use. Place it in the included fine-mesh bag in an area of steady flow. Reactors are not recommended at the start: removing organics quickly can cause a sudden increase in light intensity reaching corals. Think of it like GFO for organics and go low and slow.

Dosage (volume of blend):

• Maintenance: up to 10 mL per 10 gallons
• Corrective: up to 100 mL per 10 gallon

If your system shows elevated organics (yellow water in a white bucket test, a high SAC254 reading, or high TOC/TON on Triton N-DOC), use the corrective dosage and replace every 1–4 weeks until levels improve. Then switch to the maintenance dosage and replace monthly. Tanks with heavy feeding or bioload may need a higher dose to reach a monthly schedule.

In internal testing, 1 mL of blend per gallon reduced SAC254 by 0.5 m⁻¹ over 1 week. Results vary with the type and amount of organics in each system.

Using with ozone: place a carbon-only stage directly after your ozone source, with REDUCE DOC/ORGANICS downstream. Do not expose the resin directly to ozonated water.
