Record pool readings, chemical additions, maintenance, inventory, incidents, and export professional logs.
Trend chart uses saved pH and free-chlorine readings.

A pool chemical log creates a reliable history of water conditions, treatments, and maintenance. Regular records help operators notice trends before small changes become larger water-quality problems. A clear log also makes it easier to compare readings across different shifts, technicians, weather conditions, and bather loads. Instead of relying on memory, the operator can review exact dates, values, treatments, and follow-up notes.
Important readings often include pH, sanitizer level, alkalinity, calcium hardness, stabilizer, salt, and temperature. The correct targets depend on pool type, sanitizer system, product instructions, and local requirements. For that reason, this generator allows custom target ranges rather than forcing one universal standard. When a reading falls outside the selected range, the tool marks the record so attention can be directed toward retesting or corrective action.
Recording chemical additions is just as important as recording test results. Each treatment can include the chemical name, amount, concentration, purpose, person responsible, and estimated cost. Maintenance items such as brushing, vacuuming, filter cleaning, basket emptying, and equipment checks can be stored alongside chemistry results. This creates one practical operating record instead of several disconnected notes.
Summary values help reveal recurring conditions, frequent out-of-range results, chemical usage, and operating costs. CSV files are useful for spreadsheet analysis, while PDF reports provide a clean format for supervisors, clients, or compliance records. Local browser storage can preserve entries between visits, and JSON backup makes it easier to move records between devices. Chemical calculations should always be checked against manufacturer instructions because product strength, pool volume, testing accuracy, and water conditions can change the required dose. Accurate records also support handovers between staff and provide useful evidence when investigating recurring equipment, sanitation, or water-balance issues.
| Measurement | Typical Unit | Why It Matters | Example Editable Target |
|---|---|---|---|
| pH | pH scale | Influences swimmer comfort, sanitizer performance, and equipment protection. | 7.2–7.8 |
| Free Chlorine | ppm | Represents available chlorine used for routine sanitation. | 1–4 ppm |
| Total Alkalinity | ppm | Helps buffer pH against rapid changes. | 80–120 ppm |
| Calcium Hardness | ppm | Helps manage scaling and aggressive-water conditions. | 200–400 ppm |
| Cyanuric Acid | ppm | Helps protect chlorine from sunlight in applicable pools. | 30–50 ppm |
| Salt | ppm | Important for salt-chlorine generator operation. | Follow equipment manual |
| ORP | mV | Used by some automated systems as an oxidation indicator. | System-specific |
Reference values are examples for customizable logging. Local health codes, sanitizer systems, pool surfaces, and equipment requirements may differ.
It is a dated record of pool test readings, chemical treatments, maintenance actions, equipment observations, and follow-up notes.
Testing frequency depends on pool type, usage, sanitizer system, local rules, and operator procedures. Public or commercial facilities may require more frequent testing.
Common records include pH, sanitizer, alkalinity, calcium hardness, stabilizer, salt, temperature, filter pressure, and any system-specific readings.
Target ranges vary. Custom fields let operators match their product instructions, equipment requirements, and applicable regulations.
Yes. It includes a basic volume-and-ppm estimator. The result is approximate and must be verified against the product label.
Yes. You can add unlimited entries, duplicate the last entry, edit saved records, filter records, and remove individual rows.
Yes. The tool includes CSV download, PDF download, browser printing, and JSON backup or restore options.
No. It helps organize records and calculations but does not replace calibrated testing, manufacturer directions, local requirements, or professional judgment.
No. They are editable examples only. Always use the targets appropriate for your specific pool and jurisdiction.
Entries are stored locally in the current browser using localStorage unless you clear them. JSON backup can create a portable copy.
