ICP interpretation
An ICP report is thirty numbers and a wall of text. The hard part is knowing which three of those thirty deserve a change to your tank this week.
Most software solves this by scoring your results against its own house range. That produces the worst possible outcome: your lab says an element is fine, the app says it is high, and you are left refereeing a disagreement between two things you paid for.
Every element is judged against the range printed on your own report, from the lab that ran it. When a lab publishes a single setpoint instead of a band — as ATI and Oceamo do, and as Triton's own "Setpoint" column does — that setpoint is honoured as the target, exactly as printed. Your lab and your app agree by construction, because there is one source of truth and it is the lab's.
The PDF as it arrived from ATI, Oceamo or Triton. No re-typing, no manual entry.
Every lab names and groups things differently. Results are mapped to the lab's own scheme.
In range, below setpoint, above, or genuinely urgent — using the numbers on your report.
What to act on, what to watch, and what is noise you can ignore this month.
| Element | Your result | Lab's own target | Verdict | What it means |
|---|---|---|---|---|
| Copper | 0.009 mg/L | < 0.003 | Act now | Three times the ceiling. Invertebrates first. Run a poly-filter and re-test in ten days. |
| Iodine | 0.02 mg/L | 0.06 setpoint | Below | The lab prints one target rather than a band. Dose slowly toward it. |
| Calcium | 432 mg/L | 400–450 | In range | No action. Steady across your last three reports. |
| Phosphorus | 42 µg/L | 30–60 | In range | Fine, despite reading "high" on a generic reef chart. |

One ICP is a snapshot. Four of them is a story — accumulating metals, a trace element you have been quietly depleting for six months, or the moment a new salt mix changed your baseline.
When your Salifert alkalinity and your ICP alkalinity disagree, that usually means a kit needs replacing or a reference solution is off. The two data sets are charted against each other.
