Red Sea Trace Colours C 500ml
Red Sea Trace Colours C 500ml
Key features
- Iron plus seven metals — a broader trace metal blend than iron alone, in one supplement.
- Precise dosing reference — each 1 ml raises iron by approximately 0.01 ppm per 100 litres.
- Targets green and yellow coloration — one of four elements groups in Red Sea's coloration range, each linked to a different pigment family.
- Designed for 1:1 pairing with Trace Colors D — dosed together for a complete iron and bioactive trace element supplement.
Specifications
| Element group | Composition | Pigment target | Dosing rate | Bottle size |
|---|---|---|---|---|
| Trace Colors C | Iron, manganese, cobalt, copper, aluminium, zinc, chromium, nickel | Green / yellow | 1 ml ≈ 0.01 ppm iron per 100 L | 500 mL |
Dosage and directions
Test iron before dosing — Red Sea does not recommend a fixed daily amount for this range, since correct dosing depends on your tank's existing level and consumption rate. Use the 0.01 ppm per 100 L per ml figure to calculate a dose that brings your measured reading up to target, dosing Trace Colors D at a matching 1:1 ratio, then retest before dosing again.
Safety
Red Sea states that several of the elements in the Trace Colors range become toxic above the concentrations found in natural seawater. Don't dose on a routine schedule without testing.
Suitable for, and not suitable for
Suitable for established reef tanks running a full coral coloration program, ideally with ICP or hobbyist-grade iron testing in place. Not suitable for hobbyists without a way to test iron levels, or for fish-only tanks with no photosynthetic coral to benefit from it.
Goes well with
- Red Sea Trace Colors D — dosed 1:1 alongside this product as a matched pair.
- Red Sea Trace Colors A and B — the other two elements groups in the four-part coloration range.
- An iron or ICP test kit — needed to dose this range safely.

Common questions
Do I need to test before dosing this?
Yes — Red Sea doesn't publish a universal daily dose for Trace Colors C. Test iron first and dose to your measured deficit.
Do I have to dose this with Trace Colors D?
Red Sea designs C and D to be dosed together at a 1:1 ratio — C supplies iron and seven complementary metals, D supplies 18 further bioactive trace elements.
What are the seven complementary metals in this product?
Manganese, cobalt, copper, aluminium, zinc, chromium and nickel, alongside the iron.
Is this a substitute for Reef Foundation calcium/alkalinity/magnesium dosing?
No — Trace Colors is a coloration supplement layered on top of core reef chemistry maintenance, not a replacement for it.
