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