Fauna Marin Amin Coral Amino Acid Supplement

Fauna Marin Amin: Amino Acid Supplement for Reef Corals

Fauna Marin Amin is a daily liquid supplement built around a blend of reef-active amino acids and organic compounds formulated to support growth and color development in all coral types. The formula includes an amino acid mixture, 2-aminoethanesulfonic acid (taurine), and organic carbon skeletons that corals use as building blocks for amino acid synthesis. These compounds support the biological processes that drive coral tissue growth, pigment production, polyp extension, and recovery from stress-related fading. Fauna Marin specifically calls out Amin as a good fit for corals kept under LED lighting, where certain pigment pathways can be harder to sustain without nutritional support.

Amin is dosed daily at 0.5 ml per 100 liters, making it a low-volume, routine supplement that integrates easily into any existing dosing schedule. It is compatible with all aquarium types, including Berlin System, zeolite-based, and pellet filtration systems. The formula is not system-specific and does not require any changes to existing water chemistry programs.

Key Features:

• Amino acid blend formulated to support growth, color pigmentation, and polyp extension in SPS, LPS, and soft corals
• Contains 2-aminoethanesulfonic acid (taurine), a sulfur-based compound that supports coral tissue health and stress recovery
• Includes organic carbon skeletons that corals use as raw material for producing amino acids internally
• Supports tissue repair and recovery in corals recovering from bleaching, fading, or stress-related color loss
• Promotes aquarium biology alongside coral health, supporting the broader microbial environment in the tank
• Called out by Fauna Marin as particularly well-suited for corals kept under LED lighting
• Daily dose of 0.5 ml per 100 liters (26 US gallons) integrates easily into existing supplement schedules
• Compatible with all aquarium system types; no system modifications required

Ideal For:

• Reef hobbyists running LED lighting who want nutritional support for coral pigment development and color stability
• SPS-focused tanks where corals are under high light intensity and tissue stress recovery is a regular concern
• LPS and soft coral systems where polyp extension, tissue fullness, and vibrant color are the primary goals
• Tanks recovering from a bleaching event or coral stress where tissue repair and color regeneration are needed
• Hobbyists running low-nutrient systems who want to supplement organic compounds without adding measurable nutrients to the water column
• Aquarists looking for a straightforward daily amino acid dose that works alongside their existing two-part, Balling, or calcium reactor program without compatibility concerns

Pro Tips:

• Start at the recommended dose and hold for four weeks before evaluating results. Amino acid supplementation works gradually, and changes in polyp extension, tissue fullness, and color take time. Avoid increasing the dose early. Use 0.5 ml per 100 liters daily for a full month and observe your corals before adjusting.
• Dose consistently to maintain a steady amino acid baseline. Skipping days or dosing less frequently reduces benefits. Use an auto-doser if manual dosing isn't practical.
• Watch polyp extension as your first indicator. Improved extension often first response to amino acid supplementation, before color changes. If retracted corals extend more within 2-3 weeks, the supplement is working. Use that as your signal to stay the course.
• Do not overdose to accelerate results. Higher amino acid doses can promote nuisance algae or cyanobacterial growth, especially in tanks with high nutrients. Follow Fauna Marin dosing guidelines. If your tank has higher nutrients, monitor phosphate and nitrate for the first few weeks.
