Reef Essential® Signature Series™ / Iodine

Signature Series™ · Single-Element Precision

Iodine — for when your ICP test says you're low.

Ultra-pure, ICP-OES tested iodine with nothing else riding along — for correcting a specific deficiency your water test just flagged, not for routine blanket dosing.

Why iodine, specifically

What this element is actually doing in your tank, in plain terms.

WHY IT MATTERS

A natural sunblock

Iodine helps provide a natural sunblock effect against excess UV light and naturally moderates the density of zooxanthellae living in coral tissue.

THE PROCESS

Exoskeleton development

Iodine is used in biochemical processes that support exoskeleton development in invertebrates such as crustaceans.

PACING

Spread it over a week

The manufacturer recommends spreading the dose over at least one week, for consistency and to avoid sudden change.

When to reach for Iodine specifically

Single-element dosing is precision correction, not a routine — here's how to tell if this is the bottle you need.

USE THIS WHEN
Your ICP test flags low iodine specifically

Signature Series products exist to correct one number at a time — dose based on your actual test result, not a guess.

CONSIDER INSTEAD
Bio-Gen™ or Easy Reefer® Easy Z™

If you're not testing individual elements yet, Bio-Gen™ (Step 4) or Easy Z™ already carry iodine as part of a broader halogen blend — simpler for routine maintenance.

Dosing

Dose according to your ICP test result, not on a fixed schedule.

What you're doing Effect
Per 100L (26 US gal) dosed 0.1 mL raises Iodine by 0.01 ppm
Recommended pacing Spread the correction over at least 1 week
Target concentration 0.03 – 0.09 ppm

Rest of the Signature Series™

HALOGEN

Zooxanthellae chlorophyll.

Questions about this product

Do I need to test before dosing this?+
Yes — Signature Series products are built to correct a specific deficiency your ICP test identifies. Dosing without a baseline test risks overshooting the target range.
How is this different from the iodine in Bio-Gen™?+
Bio-Gen™ carries iodine as part of a blended halogen mix (iodine, fluoride, bromide together) for routine maintenance. This is pure, single-element iodine for correcting one specific ICP result without moving the others.
Can I use this after any ICP test, or only Quantum's?+
This product can be used after any ICP test you've purchased — it's not tied to a specific testing service. The Quantum Aqua app helps calculate your dose from the result.
What's actually in the bottle?+
Ultra-pure iodine and nothing else — formulated under controlled lab conditions with every batch ICP-OES tested for accuracy.
