Precision Water Testing for Reef Keepers
Laboratory-grade ICP-OES analysis measuring 45 elements with parts-per-billion precision, backed by NIST-traceable standards. Results within 3 days of receiving your sample.
Stop Guessing. Start Knowing.
Basic test kits only measure a handful of parameters. What about the rest of the 45 elements affecting your reef?
Our ICP-OES analysis reveals the complete picture with parts-per-billion precision, detecting elements your standard kits miss entirely.
Why Precision Matters
- Detect trace contamination before it becomes a problem
- Optimize dosing based on actual consumption rates
- Understand complex chemical interactions in your system
Common Frustrations
- Corals not thriving despite "good" parameters
- Mystery coral deaths with no obvious cause
- Slow or stunted growth patterns
- Dosing blindly without knowing consumption
- Spending money on unnecessary supplements
ICP Solutions
- Complete 45-element water analysis
- Identify hidden deficiencies and toxins
- Track consumption rates over time
- Data-driven insights
- Save money with targeted supplementation
Why Reef Labs
Built in Tampa, FL, purpose-built for reef keepers.
Reef Labs is a US-based ICP-OES laboratory engineered for the reef community. Your sample never crosses a border or waits in customs, and it isn't run through a generic water-testing pipeline — just precise chemistry from a team that keeps reefs.
3-Day Results
Results within 3 days of receiving your sample. Shipping is domestic both ways — USPS transit typically takes 2-5 days each way — so there is no waiting on international customs.
Lab You Can Trust
Tampa, FL based facility. Every run is calibrated against NIST-traceable standards and checked against certified reference materials, so the numbers you act on are the numbers in your tank.
Built for Reefs
We test the 45 elements that actually matter to coral health — macro, trace, and contaminant — with reef-specific recommendations, not generic water reports.

Understanding ICP-OES Testing
Learn how ICP-OES measures dozens of elements from a single sample, and how that can help your reef.
What is ICP-OES?
Inductively Coupled Plasma - Optical Emission Spectroscopy is an established laboratory technique that measures many elements at once with high precision.
Our instrument generates plasma temperatures exceeding 10,000 K - nearly twice as hot as the sun's surface - to break down water samples into their constituent elements.
This process allows us to detect and quantify 45 elements with parts-per-billion precision, revealing the complete chemical fingerprint of your reef system.
Why 45 Elements Matter
Standard test kits typically measure only 5-8 parameters. But reef ecosystems are complex, and trace elements play crucial roles. Here are just a few examples:
- Coral coloration and fluorescence
- Skeletal formation and growth rates
- Immune system function and disease resistance
- Photosynthetic efficiency and zooxanthellae health
Macro Elements
The building blocks of reef chemistry — calcium, magnesium, strontium and the other major ions that coral skeletons and overall water chemistry depend on.
Minor and Trace Elements
Essential micronutrients that influence coral coloration, growth, and immune function. Often depleted by protein skimming and activated carbon.
Contaminants and Toxins
Potentially harmful elements that can accumulate from salt mixes, supplements, or source water. Early detection prevents livestock losses.
ppb Precision
Trace elements measured to parts per billion
NIST-Traceable Standards
Every run calibrated against NIST-traceable standards and checked against certified reference materials
