Maintaining a healthy reef aquarium involves more than testing calcium and alkalinity. Trace elements, heavy metals, and macro/minor ions all play essential roles in coral vitality and ecosystem stability. That’s where Reef Zlements ICP Tests shine—offering a deep dive into your water chemistry through precise lab-based analysis.
But receiving a detailed ICP report is just the first step. To make the most of your results, you need to understand what you’re looking at—and know how to respond. In this guide, we’ll walk through how to read your Reef Zlements ICP test results and translate the data into actionable dosing strategies.
Understanding Your ICP Test Report
After sending your sample to Reef Zlements’ UK-based lab, your results will be uploaded to your personal online dashboard. Here’s what you’ll find:
1. Elemental Breakdown by Category
Your report is divided into groups:
-
Macronutrients (e.g. Calcium, Magnesium, Potassium)
-
Trace Elements (e.g. Iodine, Iron, Zinc)
-
Contaminants/Heavy Metals (e.g. Aluminium, Copper, Tin, Nickel)
-
Salinity-Linked Elements (e.g. Sodium, Chloride, Sulfate)
Each element includes:
-
Your tank’s current reading
-
Natural seawater (NSW) reference level
-
A green/yellow/red indicator showing if the value is optimal, deficient, or excessive
2. Visual Charts and Color Coding
Your dashboard presents results in easy-to-read bar graphs and color-coded indicators:
-
Green means the element is within the recommended range
-
Yellow indicates a mild deviation (usually correctable with minor adjustments)
-
Red highlights a potentially harmful level requiring immediate action
This visual system makes it simple to spot problem areas even if you’re new to reef chemistry.
Key Elements to Prioritize in Your Analysis
Calcium, Magnesium, and Alkalinity
These form the backbone of coral skeletons. Even if these levels seem acceptable in hobby-grade tests, ICP tests can reveal subtle imbalances that affect coral growth over time.
Strontium, Iodine, and Potassium
Essential for tissue development, color, and immune response. Low levels can reduce polyp extension and overall coral health.
Iron, Zinc, and Manganese
Vital micronutrients for zooxanthellae photosynthesis. Deficiencies may lead to dull coloration or slowed growth in photosynthetic corals.
Contaminants like Aluminium, Copper, and Nickel
These often stem from RODI system leaks, rusting metal components, or contaminated additives. Even in tiny amounts, they can stress corals and inverts.
How to Respond to Abnormal Results
1. Dosing Based on Reef Zlements Recommendations
Each result includes tailored guidance on how much of a specific Reef Zlements additive to dose in order to restore optimal levels. Because their product line is built around the ICP system, you can take the guesswork out of correction.
2. Use RO/DI Water Testing for Source Analysis
If contaminants are detected, perform a companion RO/DI water ICP test (some kits include RO vials). This can identify whether issues stem from your source water, filters, or the tank itself.
3. Addressing Heavy Metal Contamination
For elevated metals:
-
Check pumps, magnets, frag racks, and heaters for corrosion
-
Swap out suspect components for reef-safe alternatives
-
Run activated carbon or specific metal-binding resins
-
Conduct small water changes over several days to dilute
4. Adjusting Major Ion Balance
For calcium, magnesium, and potassium imbalances:
-
Use Reef Zlements foundational elements (e.g. Z-Calcium, Z-Magnesium)
-
Match the dosing advice in your ICP dashboard exactly
-
Monitor via home test kits between ICP tests to track stability
5. Don’t React Too Quickly
Minor deviations (yellow zone) often self-correct with routine maintenance and regular feeding. Only dose when there is a clear trend or red flag in the data. Overcorrecting can cause swings that stress your livestock.
When to Retest
It’s a good practice to:
-
Retest 2–3 weeks after corrective dosing to verify changes
-
Perform ICP tests every 4–6 weeks as part of your reef care routine
-
Test after major changes such as dosing regimen shifts, new livestock, or suspected contamination events
Tips for Getting the Most Out of Your ICP Tests
-
Always shake additives well before dosing, especially trace element solutions
-
Use a digital scale or syringe to ensure precise dosing
-
Avoid mixing multiple additives at once—spread doses across the week
-
Log your actions and note visible changes in coral behavior, polyp extension, or coloration
