- What is Seachem Marine Trace used for?
- It replenishes trace elements in saltwater aquariums. These elements are depleted by use, oxidation and precipitation, and fish get some of them from the water as well as from food.
- How much should I dose?
- Use one capful, about 5 mL, for every 20 US gallons twice a week. Keep the dose steady rather than adding extra to make up for missed days.
- Does it replace calcium or alkalinity supplements?
- No. It supplies trace elements only. Calcium, alkalinity and magnesium still need their own dosing and testing.
- Is it for fish-only tanks or reefs?
- Both. It is formulated around elements required by fish, and it also supports coloring and growth in corals, anemones and other photosynthetic animals.
- Can I overdose it?
- Yes. Trace elements build up if you add more than the tank uses, so follow the label dose and test where you can.
- How does it differ from an all-in-one reef supplement?
- It is narrower and fish-focused, with only elements shown to be required by fish. All-in-one products usually bundle major elements too.
