You take pool care seriously. Thank you for using Pool Calcs. Keep measurements, water tests and service history together, whether you maintain your backyard pool or look after customers. POOL VOLUME AND USEFUL CALCULATORS Get a volume estimate before planning water care or equipment work. - Calculate circular, rectangular and square pool volumes. - Work with elliptical, oval, free form and bean shaped pools. - Use American or Metric measurements. - Convert area, distance, volume, flow rate and pressure. - Convert temperatures and estimate rainwater collection. - Check a Langelier Saturation Index estimate for water balance. WATER TESTS AND CHEMICAL RECORDS Build a pool care log you can refer to on the next visit. - Record chlorine, pH, alkalinity, calcium hardness and cyanuric acid. - Track salt, water temperature, test dates and notes. - See previous readings beside separate current entry fields. - Estimate supported dry pool-salt additions using your chosen target. - Keep the proposed amount separate from what you actually apply. - Retain product strength and the details behind a saved salt calculation. PRODUCTS YOU USE OFTEN Keep familiar chemicals and purchase details ready for your next visit. - Save ingredients, concentration, package sizes, units and prices. - Keep favorite products close at hand. - Copy product details into treatment records. - Keep past product details when catalog prices change. - Use other products for manual logging when a calculation is unsupported. SERVICE VISITS AND DAILY ROUTES Keep the job's notes together from the first reading to the report. - Add readings, treatments, tasks, photos and notes to one visit. - Recover unfinished working text with automatic draft saving. - Preview a report before completing the visit. - Share service reports with your business and contact details. - Arrange a day's stops without changing the standing order. - Open directions to each pool's own service address. - Resume unfinished visits or skip and reschedule work with a reason. - Schedule recurring service and equipment tasks with optional local reminders. HISTORY THAT HELPS YOU PLAN Use your pool maintenance records to review what happened and when. - Follow water chemistry trends and compare pools. - See treatment and maintenance dates beside readings. - Record clean-filter pressure baselines in psi, kPa or bar. - Compare pressure readings for the same equipment and operating context. - Review actual chemical consumption by pool and period. - See recorded chemical costs grouped by currency. - Review visit revenue and direct labor with clear currency coverage. Unknown units, missing costs and unrecorded currencies stay visible alongside the totals. Trend markers show when work happened, without claiming it caused a reading to change.
