Seachem Marine Trace replenishes essential trace elements in marine aquariums, supporting fish health, growth, and natural colouring. Unlike terrestrial animals, fish absorb nutrients from both their food and surrounding water. These elements are depleted over time through biological processes, oxidation, and precipitation, making regular supplementation important for maintaining optimal water conditions.

Available Sizes:

• Seachem Marine Trace 500ml

Key Features:

• Supplies essential trace elements required by marine fish
• Supports healthy growth, metabolism, and pigmentation
• Promotes vibrant colouring in corals and invertebrates
• Safe and effective for marine aquariums
• Easy-to-use liquid formula

Use 5ml (1 capful) for every 80 litres (20 gallons) of aquarium water twice weekly. Regular use helps sustain a healthy, balanced environment for marine life, including fish, corals, and other invertebrates.
