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 — both directly tied to coral color and stress resistance.

THE PROCESS

Exoskeleton development

Iodine is used in biochemical processes that support exoskeleton development in invertebrates such as crustaceans — shrimp, crabs, and other molting inverts rely on it during each molt cycle.

WHO NEEDS MORE

Inverts & heavy bioload

Tanks with a meaningful cleanup crew or ornamental shrimp population burn through iodine faster than coral-only systems — worth checking first if your ICP test came back low.

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

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.
