Seachem Reef Nitrogen 250 mL

Seachem Reef Nitrogen is a concentrated nitrogen supplement formulated specifically for reef aquariums with low or undetectable nitrate levels. In ultra-low nutrient systems (ULNS), nitrogen depletion can lead to pale corals, reduced growth, and poor polyp extensionespecially in SPS-dominant tanks.

Reef Nitrogen provides nitrogen in multiple bioavailable forms, allowing reef keepers to safely and precisely raise nitrate levels to support healthy coral metabolism, coloration, and growth without destabilizing the system.

The 250 mL bottle is ideal for home reef aquariums and controlled nutrient dosing.

Q: Can this cause algae blooms?
A: Overdosing can contribute to algae; proper testing prevents this.

Q: Is this safe for mixed reef tanks?
A: Yessafe for SPS, LPS, soft corals, fish, and invertebrates when used correctly.

Q: Should Reef Nitrogen be used with Reef Phosphorus?
