Thank you for using Pool Calcs and for the care you put into every pool. Your careful readings and service notes make each pool's history more useful. This update connects your water tests, visit notes and plans for the next job. CONNECT TESTING AND ACTUAL TREATMENTS - Plan supported salt adjustments from a saved test and confirmed pool volume. - Choose your target and a supported dry pool-salt strength. - Keep the calculation details with the saved proposal. - Record the amount you actually applied as a separate treatment. - Keep manual treatment entry available for other pool chemicals. - Keep proposed quantities out of actual chemical consumption and costs. FINISH A VISIT WITH LESS REPEATED ENTRY - See previous readings beside separate current-value fields. - Keep treatments, tasks, photos and notes with the same visit. - Save unfinished working text automatically while you work. - Resume an existing visit without starting its records again. - Preview a draft report before completion. - Review and share your saved report. - Keep unfinished treatment rows for later review rather than recording them as applied. SAVE FAMILIAR PRODUCTS - Keep ingredients, concentration, package size, units and cost in a product library. - Choose favorite products when adding a treatment. - Retain the original product details in your treatment history. - Record purchase details that differ from the catalog price. - See when a price, unit or currency is missing. PLAN RECURRING WORK AND DAILY STOPS - Set recurring service visits and equipment tasks. - Choose whether supported schedules follow the planned date or completion. - Use optional local reminders, snooze and overdue status. - Reorder a day's stops with drag or move controls. - Keep the standing order for other days. - Open directions to the individual pool's service address. - Add a missing address without blocking the visit. - Skip or reschedule work with a reason while retaining its history. - Edit a reopened visit's history without completing it again. BRING YOUR EXISTING HISTORY - Import water tests, treatments, maintenance and visits, including notes, from supported CSV layouts. - Map columns and review dates, units and pool matches before saving. - Review duplicate candidates and choose what to skip or keep separately. - Reuse saved mapping choices for a familiar spreadsheet. - Keep the original source file for reference. - Export source copies separately from your full record backup. - See the original import summary when retrying the same file and choices. SEE MORE IN YOUR RECORDS - Show saved treatment and maintenance dates on chemistry trends. - Open an event to review the original record. - Keep readings with different or unknown units in separate groups. - Record clean-filter baselines and pressure observations in psi, kPa or bar. - Compare the same equipment and operating conditions. - Review actual chemical use and direct costs by pool and period. - Separate known currencies and show gaps in cost coverage. - See when missing currency details prevent a comparable contribution total. EVERYDAY FIXES - Keep recorded chemical amounts visible when a unit conversion is out of range. - Keep trends and cost totals consistent while you review longer histories. - Give clearer feedback when Maps cannot open. - Keep skipped, closed and reopened work easier to distinguish. - Get clearer warnings when imported records conflict with saved history. - Keep recurring-work history available when a visit needs review. Your pool volume calculators, converters, water balance tools, customer records, equipment details and sharing options remain available. Thank you for keeping your records with Pool Calcs.
