Reef Essential® Signature Series™ / Bromine

Signature Series™ · Single-Element Precision

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

Ultra-pure, ICP-OES tested bromine on its own — for correcting a specific deficiency your water test just flagged, not for routine blanket dosing.

Why bromine, specifically

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

WHY IT MATTERS

A skeleton-building halogen

Bromine is present in coral skeleton, helping to improve calcification and produce strong aragonite instead of brittle calcite — the same structural role fluorine and boron play.

THE PROCESS

Enzyme production

Zooxanthellae require bromine for the production of key enzymes used in many biochemical processes — it's not just structural, it's metabolic.

WHO NEEDS MORE

Dense SPS & zooxanthellae load

Fast-growing stony coral systems and tanks with heavy zooxanthellae density burn through bromine faster than a fish-only or LPS-light system.

When to reach for Bromine 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 bromine specifically

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

CONSIDER INSTEAD

A blended maintenance product instead

Bio-Gen™ or Easy Reefer® Easy Z™ already carry bromine 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	2 mL raises Bromine by 1 ppm
Recommended pacing	Spread the correction over at least 1 week
Target concentration	0.03 – 0.09 ppm

Rest of the Signature Series™

Organized by periodic table group — dose only the elements your ICP test says you're missing.

Fluorine

Calcification & parasite resistance.

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 bromine in Easy Z™?+

Easy Z™ carries bromine as part of a blended alkalinity/trace-element mix for routine maintenance. This is pure, single-element bromine 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 bromine and nothing else — formulated under controlled lab conditions with every batch ICP-OES tested for accuracy.
