Reef Essential® Signature Series™ / Molybdenum
Signature Series™ · Single-Element Precision
Molybdenum — for when your ICP test says you're low.
Ultra-pure, ICP-OES tested molybdenum on its own — for correcting a specific deficiency your water test just flagged, not for routine blanket dosing.
Why molybdenum, specifically
What this element is actually doing in your tank, in plain terms.
Coral health and color
Molybdenum is an essential element required for coral health and vitality, and it improves color.
Macroalgae & nutrient export
Molybdenum also aids macroalgae growth, which naturally reduces unwanted nutrients in the aquarium while providing oxygen, expelling carbon dioxide, and improving pH stability.
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 Molybdenum 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 molybdenum 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
Easy Reefer® Easy E™ already carries molybdenum as part of a broader calcium/trace-element 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 | 1 mL raises Molybdenum by 0.001 ppm |
| Recommended pacing | Spread the correction over at least 1 week |
| Target concentration | 0.004–0.006 ppm |
Rest of the Signature Series™
Organized by periodic table group — dose only the elements your ICP test says you're missing.
