Seachem Reef Trace – Essential Trace Elements for Vivid Reefs

Replenish the Trace Elements Your Reef Runs Out Of

Trace elements are constantly depleted through utilization, oxidation, and precipitation — and once they're gone, coral color fades and growth slows.

Reef Trace is a scientifically formulated solution built specifically for complex reef aquariums. It provides a broad range of essential trace elements that create the ideal environment for the growth, development, and increased coloration of marine fish, corals, and invertebrates, keeping your tank healthy and well balanced.

That scientific formulation reflects its maker: Seachem Laboratories, a chemistry-driven company founded in 1979 in Madison, Georgia, where products are developed in-house by chemists rather than assembled from generic premixes. Reef Trace is designed to work as the trace-element component of Seachem's coordinated reef system, complementing calcium, alkalinity, magnesium, and coral nutrition supplements so that the full spectrum of elements your reef consumes is replenished together rather than in isolation.

1. Shake and measure 1 capful (5 mL) of Reef Trace for every 80 L (20 US gallons) of aquarium water.
2. Dose twice a week to keep trace elements replenished.
3. Watch coloration and growth improve as depleted elements are restored.

Bring your reef's color back to life. Add to cart.

Why Seachem Reef Trace

• Restores the elements reefs deplete: replenishes a broad range of trace elements lost to utilization, oxidation, and precipitation, supporting growth, development, and coloration.
• Broad-spectrum formula: supplies many essential trace elements in one solution rather than a single ingredient, targeting the ideal environment for fish, corals, and invertebrates.
• Part of Seachem's reef system: designed to complement calcium, alkalinity, magnesium, and coral-nutrition supplements for balanced overall water chemistry.
• Bioavailable trace elements: provides elements in forms marine life can readily take up and use for color and vitality.

Best For

Established and complex reef aquariums keeping colorful SPS, LPS, and soft corals plus invertebrates, where full-spectrum trace-element replenishment supports vivid coloration and steady growth.

FAQ

How often should I dose Reef Trace? Use 1 capful (5 mL) for every 80 L (20 US gallons) of aquarium water twice a week to keep depleted trace elements replenished.

How does this fit with my other reef supplements? Reef Trace covers trace elements and is built to work alongside Seachem's calcium, alkalinity, magnesium, and coral-food products, so it complements rather than replaces those parts of the reef system.

Is it reef-safe? Yes. Reef Trace is scientifically formulated specifically for complex reef aquariums housing marine fish, corals, and invertebrates.

What It Does

Provides a broad range of essential trace elements that create an environment ideal for the growth, development, and increased coloration of a variety of marine fish, corals, and invertebrates.
