Red Sea Trace Colours D 500ml
Red Sea Trace Colours D 500ml
Key features
- 18 bioactive trace elements — the broadest of the four Trace Colors formulas, covering elements not addressed by A, B or C.
- Targets purple and blue 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 C — dosed together for a complete iron and bioactive trace element supplement.
- Completes the A/B/C/D range — the fourth and final part of Red Sea's coral coloration program.
Specifications
| Element group | Composition | Pigment target | Dosing rate | Bottle size |
|---|---|---|---|---|
| Trace Colors D | 18 bioactive trace elements | Purple / blue | Dosed 1:1 with Trace Colors C | 500 mL |
Dosage and directions
Dose Trace Colors D at a 1:1 ratio alongside Trace Colors C, matching whatever volume of C you've calculated from your measured iron reading. Red Sea does not recommend dosing this range on a fixed schedule independent of testing.
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 already dosing Trace Colors C, running a full coral coloration program with ICP or hobbyist-grade trace element testing in place. Not suitable as a standalone product without Trace Colors C, or for fish-only tanks with no photosynthetic coral to benefit from it.
Goes well with
- Red Sea Trace Colors C — 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 ICP or trace element test kit — needed to dose this range safely.
Warranty and delivery
Covered by Red Sea's standard product guarantee in addition to your rights under Australian Consumer Law. Ships as a standard parcel; no cold-chain requirement.
Common questions
Can I dose this without Trace Colors C?
Red Sea designs D to be dosed 1:1 with C — using D alone isn't the intended use of the product.
What's in the 18 bioactive trace elements?
Red Sea doesn't publish the individual element list for D beyond describing it as 18 further bioactive trace elements, distinct from the halogens in A, the potassium/boron in B, and the iron and seven metals in C.
How much do I dose?
Match whatever volume of Trace Colors C you're dosing, based on your measured iron deficit — there's no separate fixed schedule for D.
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.
