The minimum a report should contain
Date and time of the visit, so you know when someone was actually there.
Digital readings of your core levels: free chlorine, pH, total alkalinity, calcium hardness, cyanuric acid, salt where applicable, and water temperature.
The LSI result those numbers produce, not just the raw values.
Every chemical added and how much of it.
Which tasks were completed — brushing, baskets, cleaner, filter pressure, equipment check.
Notes and photos of anything developing.
Why the trend matters more than any single visit
One reading is a snapshot. Twelve weeks of readings tell you your pool is slowly losing calcium, or that CYA has climbed past useful, or that filter pressure is creeping toward a clean.
That history is also what protects you at resale, at warranty time on a heater or salt cell, and any time someone claims damage was sudden.
How we do it
Every stop is checked into an app on arrival and closed out on departure. Readings, doses, completed tasks, and notes go in on site, not from memory at the end of the day.
You get that report after every visit. Arrival notifications are available too, so you can move a dog, a contractor, or a nap before we open the gate.
