Seachem Marine Trace 500 ml

Marine Trace supplies a broad range of trace elements demonstrated to be necessary for proper fish health and growth. Unlike terrestrial animals, fish obtain nutrients from both their food and environment. Trace elements are normally depleted by utilization, oxidation and precipitation, thus it is important to restore them on a regular basis. Marine Trace contains only those elements actually demonstrated to be required by fish. Replenishment of a number of trace elements is required to maintain an environment ideal for the growth and reproduction of marine life, but while the importance of trace elements has been recognized by aquarists for many years, the physiological reasons are not fully understood. The chemical elements in seawater are varied, and, likewise their addition to the aquarium in trace quantities has varied effects on a variety of saltwater plant and invertebrate species. In general, though, these elements are important for metabolic processes and pigment formation. Addition of iron, for instance, has been shown to benefit coloring and growth for corals, anenomes, and other photosynthetic animals.

Use 1 capful (5 mL) for every 80 L (20 gallons*) twice a week.

Amounts per 1 gram. Ingredients: calcium chloride, magnesium chloride, potassium iodide, copper sulfate, iron sulfate, zinc sulfate, manganese sulfate, sodium fluoride, selenium AAC

Compatibility

What it is. A trace-element supplement built around the elements Seachem says are actually demonstrated to be needed by marine fish, rather than a broad, unproven mineral blend. Its main ingredients are calcium and magnesium chloride carrying iodide, potassium, copper, iron, zinc, manganese, fluoride and selenium.

Where this sits in the Seachem range. Seachem’s own distinction from Reef Trace: Reef Trace’s mineral levels are pitched at corals and other invertebrates, while Marine Trace is pitched at what benefits marine fish specifically. Trace elements deplete steadily through use, oxidation and precipitation, which is why Seachem positions this as a regular top-up rather than a one-off dose.

Dosage & Directions

Seachem’s own dose. 1 capful (5 ml) per 80 L (20 US gallons), twice a week.
