A quick decision brief for this specific tool
Inputs that matter
One named and revisioned completed total-hardness report reconciliation; one exact completed sample identity and source-owned collection record; exact total/general-hardness property wording expressed as CaCO3 equivalent; completed source report, revision and exact row; source method, expression basis and responsible reviewer; one nonnegative source value independently tagged mg/L as CaCO3, mmol/L CaCO3 equivalent or °dH/°dGH; optional independent same-sample/same-property/same-method-basis reported value with its own supported unit and exact source; optional owner arithmetic tolerance in mg/L as CaCO3; plus explicit completed-report, total-hardness-only, unchanged-scope, same-property-conversion-only and completed-reconciliation-only boundaries
Output to expect
The same retained total-hardness-as-CaCO3 property in mg/L, mmol/L CaCO3 equivalent and °dH/°dGH; optional independently normalized reported value, signed reported-minus-reproduced residual and inside/outside owner-tolerance state; complete sample/report/row/method/expression/reviewer evidence; deliberate page-session retention, copy/Markdown/print/share actions; and stable Project outputs that keep alkalinity/KH/carbonate-hardness/TDS/conductivity/salinity/elemental conversion, composition/density/method-equivalence/water-quality inference, classification/aquarium targets, mixing/dosing/buffering/remineralization/treatment, sampling/laboratory/kit/report validation and health/safety/regulatory/compliance approval false
How it works
Validate one coherent completed report record and preserve the source-owned property/expression basis; normalize mg/L as CaCO3 directly, mmol/L CaCO3 equivalent with NIST molecular weight100.087, or °dH/°dGH with17.85mg/L as CaCO3 per degree; reproduce the other two labeled representations; then optionally normalize one independently reported same-scope value and calculate its signed mg/L-as-CaCO3 residual inside a reviewer-owned arithmetic tolerance using only machine-scale boundary allowance
The exact sample, collection record, report/revision/row, total-hardness property wording, method, CaCO3-equivalent expression basis, source unit and reviewer must travel together. Bare ppm, another sample, mixed result, target/estimate/incomplete report, changed method/basis or unknown scope requires another responsible workflow or is refused.
A shared CaCO3-equivalent expression unit does not make different water properties interchangeable. Keep alkalinity/KH/carbonate hardness, TDS/conductivity/salinity, elemental calcium/magnesium, composition, density, measurement uncertainty, calibration and method equivalence outside this arithmetic record.
Converted arithmetic is not a water-quality, aquarium-care or treatment decision. Keep classifications, species/plant/livestock targets, RO mixing, dosing, buffering, remineralization, treatment, sampling/laboratory/kit/report validation, health, safety, regulatory and compliance decisions with current exact evidence and accountable qualified reviewers.
Choose your path
Built around the job you need to finish
Reconcile one completed source-owned total/general-hardness result explicitly expressed as CaCO3 equivalent across mg/L, mmol/L-equivalent and °dH/°dGH while preserving the exact sample/report/method/expression basis and refusing cross-property, aquarium-care, treatment, health, safety and compliance inference.
Water-report reviewer reproducing one completed hardness row
Normalize one exact total-hardness result without losing its sample identity, report row, method, CaCO3-equivalent expression basis or reviewer responsibility.
Name and revision the record, retain the exact sample/collection and completed report evidence, enter the source value with its explicit supported unit, affirm all boundaries, then reconcile.
Receives three clearly labeled representations of the same retained property while every provenance field and nondecision remains visible.
Independent worksheet reviewer checking another unit
Compare a same-sample same-property reported °dH or mmol/L value without treating arithmetic agreement as method, laboratory, kit or report validation.
Enter the independent value, unit and exact source, optionally add an owner arithmetic tolerance, inspect the signed residual, retain a snapshot, edit the live source value and verify stale-result removal.
Can distinguish same-property arithmetic from uncertainty, water quality or approval, with retained evidence immutable and tolerance neutral when absent.
Phone user testing the former aquarium-hardness promise
Avoid a fabricated KH conversion, soft/hard classification, species target, RO mix, buffer, dose or treatment instruction.
Load the clearly static example, trigger target/incomplete, KH/TDS/elemental, mixed-scope, cross-property and decision refusals, recover with one completed total-hardness report, reconcile, retain and Reset.
Unsupported requests fail at their owning field with no stale result/action, and the Tool supplies only completed same-property report arithmetic.
Authoritative checks for this tool
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.
Bind the arithmetic to one exact sample identity, completed report and row, source method, revision, total-hardness-as-CaCO3 expression basis and responsible reviewer. A target, estimate, mixed sample or changed method needs another record and is refused here.
one sample + one report row + one method + one expression basis
Normalize the same reported property
Convert only total hardness expressed as CaCO3 equivalent. Use 100.087 g/mol for the CaCO3-equivalent amount representation and 17.85 mg/L as CaCO3 per German degree. The labels remain attached to every output so the arithmetic cannot silently change property.
An optional independently reported value must describe the same completed sample, property, method and expression basis. Its signed residual and optional owner arithmetic tolerance are record checks only—not water classification, suitability, treatment or compliance thresholds.

Example Scenarios
A reviewer retains one exact completed total-hardness row and reproduces its same-property mmol/L-equivalent and °dH representations without changing the report's analyte/property basis.
A second source reports the same completed total-hardness result in °dH. The reviewer preserves that source and inspects a signed mg/L-as-CaCO3 residual without treating agreement as method or report validation.
The workflow refuses cross-property conversion and care decisions. It does not turn alkalinity/KH, TDS, conductivity, salinity or elemental calcium/magnesium into total hardness and does not propose mixing, dosing or livestock targets.
Common Mistakes to Avoid
✕
Converting a KH, alkalinity, TDS or elemental result as total hardness
✓
Stop and retain the actual reported property. Do not use a shared unit label to cross analyte/property boundaries; create a separate evidence-backed workflow for the real property.
✕
Using a converted number as an aquarium or treatment instruction
✓
Keep the output as completed report arithmetic. Do not infer species suitability, RO mix, buffering, dosing, remineralization, health, safety or compliance from this record.
FAQ
Only one completed total/general-hardness result whose source explicitly expresses the property as CaCO3 equivalent. It reproduces the same retained property in mg/L as CaCO3, mmol/L CaCO3 equivalent and °dH/°dGH.
Not as a bare unit. ppm can depend on the source's quantity and solution basis. Retain the exact report wording; use this workflow only when the source explicitly reports one of the supported total-hardness-as-CaCO3 units.
No. This record accepts total/general hardness expressed as CaCO3 equivalent and explicitly refuses alkalinity/KH or carbonate-hardness substitution. Sharing an expression unit does not make different properties equivalent.
No. It reports same-property arithmetic only. Classification, species or plant targets, mixing, dosing, buffering, remineralization and treatment require separate current evidence and accountable decisions.
No. The residual only reproduces source-owned arithmetic for the same retained scope. It does not validate sampling, uncertainty, calibration, a method, laboratory, kit, report, health use, safety or compliance.
About Reviewed Completed Total-Hardness Report Unit Reconciliation
Reconcile one completed, source-owned total/general-hardness result only when the report explicitly expresses that same property as CaCO3 equivalent. Retain the exact sample, report row, method, expression basis and reviewer; this workflow does not reinterpret alkalinity/KH, TDS, conductivity, salinity or elemental results and does not make aquarium-care or treatment decisions.
