Seachem Fresh Trace – Trace Element Supplement for Freshwater Aquariums

Restore the trace elements freshwater fish quietly lose.

Fish take up nutrients from their environment as well as their food — and trace elements are steadily depleted by use, oxidation, and precipitation, leaving your community tank short.

Seachem Fresh Trace replenishes a broad range of trace elements scientifically demonstrated to be necessary for fish health and growth — only the elements fish actually need.

Seachem Laboratories has engineered aquarium water chemistry since 1979 from its labs in Madison, Georgia, where in-house chemists formulate products that work together as a system. Fresh Trace applies that evidence-led approach to the everyday community tank: it supplies only the trace elements shown to matter for fish, giving general freshwater aquariums a simple way to keep trace levels topped up between water changes.

1. Dose 5 mL (1 capful) per 80 L (20 gallons) twice a week.
2. Add directly to the aquarium.
3. Pair with regular water changes and a quality diet.

Why Seachem Fresh Trace

• Evidence-based elements: supplies only the trace elements scientifically demonstrated to be necessary for fish health and growth.
• Replaces what's lost: restores traces depleted by use, oxidation, and precipitation between water changes.
• For any community tank: a general-purpose freshwater supplement, not tied to one species group.
• Simple twice-weekly dosing: one capful per 80 L, added straight to the tank.

Best For

General freshwater community aquariums — tropical community fish, livebearers, tetras, and mixed tanks — that need trace elements replenished between changes.

FAQ

Who is this for? Any general freshwater community aquarium; unlike Cichlid Trace or Discus Trace, it isn't tuned to one species group.

Do I still need water changes? Yes — Fresh Trace tops up depleted trace elements between changes; pair it with regular water changes and a quality diet rather than using it in their place.

How much and how often do I dose? 1 capful (5 mL) per 80 L (20 US gallons) twice a week, added directly to the aquarium.
