    Wardens

    Used for the data-entry selector, staff list, alerts, and exports.

      Site profile

      Set the site identity, guidance profile, and treatment-learning options.

      PNG, JPEG, or WebP; maximum 1 MB, 96–2000 px per side, square or near-square.

      Use country- or jurisdiction-specific guidelines.

      Used for scheduled checks and alerts.

      Previous results show how this facility responded to recorded treatments. With enough consistent follow-up data, AquaLedger can also suggest a dose; it is never applied automatically.

      Set up pool facilities

      Open each pool and work from its identity and capacity through the applicable guidance starting point, targets, schedule, equipment, and assurance checks.

      Set up hot-tub facilities

      Open each hot tub and work from its identity and capacity through the applicable guidance starting point, targets, schedule, equipment, and assurance checks.

      Operating procedures

      Review the AquaLedger starting text, customise it for this site where needed, and add a facility override only when one facility works differently.

      Versioned procedure library Draft procedures are not approved instructions. Enable only a reviewed procedure intended for operators.

      A facility procedure overrides its facility-type procedure, which overrides the whole-site procedure. Each method is reviewed and versioned separately.

      Existing whole-operation procedures

      These remain available during staging comparison. They have not been replaced on the live site.

      Platform defaults are starting templates for all sites. Only an AquaLedger super-admin can change them.

      Season status

      Close a facility during its off season. Opening records a commissioning event; record any shock treatment as a normal treatment entry after opening.

      Total alkalinity

      Total alkalinity shows how strongly the water resists pH change. It is optional on routine checks, but AquaLedger requires it when the site's scheduled or event-triggered full-chemistry check is due. UK PWTAG pool guidance uses 80–200 ppm as CaCO₃ and weekly testing. For hot tubs, HSG282 treats total alkalinity as a water-balance factor but does not prescribe a numerical range or universal interval; the configured schedule and targets form the site's risk-assessed testing programme.

      Hot-tub readings outside the preferred range are advisory. Readings beyond the wider action limits require a response. Total alkalinity alone does not close a facility.

      Additional chemistry checks

      These checks are optional and hidden unless enabled. Cyanuric acid and combined chlorine are not shown for bromine-treated facilities.

      Advanced shared hot-tub fallback settings Only used where a facility field is left blank. Show

      These advanced template values are used only where an individual hot-tub field is left blank.

      The selected compliance profile controls jurisdiction-specific wording. AquaLedger uses the configured visitor and day thresholds for water-change prompts; set these to match the local rules and site procedure.

      Shared fallback hours

      Used only by hot tubs whose operating pattern is set to “Use shared fallback hours”.

      Used to tell staff whether treatment can settle before opening, needs urgent retesting during use, or can rebalance overnight.

      Operational reminder shown after dosing. Check the product label and site procedure if they specify a longer wait.

      Use the default target and tolerance to flag readings that are materially off-temperature. Use your typical refill-water temperature so AquaLedger can estimate when a drained hot tub will be back up to service temperature.

      Advanced shared pool fallback settings Only used where a facility field is left blank. Show

      Used only where an individual pool volume is left blank.

      Shared fallback hours

      Used only by pools whose operating pattern is set to “Use shared fallback hours”.

      Used by the decision card to distinguish pre-opening, open-hours, and closing treatment windows.

      Operational reminder shown after dosing. Check the product label and site procedure if they specify a longer wait.

      Pool temperatures outside the configured target band are flagged as operational warnings in logs and exports.

      Treatment products

      Enable the products you actually keep on site, name each one as the exact product on the container, and set the dose guide from that product label so logs, learning, and live guidance match the stock used at the time.

      Configure the Shock treatment product with the chemical name, unit, and label dose. Routine shock reminder frequency is set per hot tub in Hot tubs.

      Critical alerts

      Emails are for unresolved safety risks. A later recovery record resolves the alert; acknowledgement alone does not.

        Alert rules

        All alerts remain in the manager ledger. Untick Email to silence that immediate email type.

        Manager reports

        Every recipient receives the existing monthly report with CSV records and its analysis PDF. Choose whether they also receive a daily or weekly exception email; no exception email is sent when there is nothing to report.

        Scheduled CSV reports run on the first day of each month and cover the previous full calendar month.

          Facility logs default to 5 rows; setup history shows 4.

          Set each required check window. Enable a missed-check alert only where manager action is needed.

          Data

          Staging-only tool that replaces operational water entries with synthetic test data.

          Deletes operational water entries while retaining setup history and configuration.

          Deletes water entries and setup history for this site, then resets filter and water-change dates.

          Sites

          Platform-level site management for AquaLedger super-admins. Sites are archived rather than deleted so historical logs remain intact.

          Compliance-reference reviews

          Platform-admin review of detected HSE and PWTAG source changes. A decision is recorded for audit purposes and never changes site guidance automatically.

          Critical alerts

          Acknowledge to record manager review. Recovery evidence resolves the alert.
