What this sheet is for
Keep a unit that is used hard in short bursts on a daily row, so the pattern between sessions, readings and cartridge cleans is visible rather than guessed.
Who it is for
Owners of a swim spa, cold plunge or heated plunge pool at home, at a holiday let or in a small gym or studio.
How to use it
- Write in the unit type, volume and plant, and the ranges from your manufacturer and the rules where you are.
- Each day, write the temperature, sanitiser and pH exactly as your kit reads them.
- Count the sessions or users since the last row — the load is what moves the water.
- Note the current pump or chiller behaviour, whether the cartridge was rinsed or swapped, and any water added.
- Record what was dosed or done, and that the cover went back on.
What is on the sheet
One page, top to bottom:
Printed under the title: A swim spa or plunge pool is neither a pool nor a hot tub — a few thousand litres, a current pump or a chiller, heavy use in short bursts. This log tracks the water, the sessions and the plant on one row.
Your ranges, written in once. No target readings are printed here. Your sanitiser and pH ranges, the water temperature you run at and how often the cartridge comes out are set by your manufacturer and the rules where you are — write them in the boxes so every row below has something to be read against.
Write-on lines: Unit / property · Type (swim spa, cold or heated plunge) · Volume · Heater or chiller make · Sanitiser range (whose figure) · pH range (whose figure) · Running temp (whose figure) · Cartridge clean interval (whose)

Questions
Why not just use the Hot Tub Water Care Log?
A swim spa holds several times the water, runs a current pump and takes a different kind of use; a cold plunge runs a chiller and no heater at all. The columns here follow that — sessions, the pump or chiller, the cartridge — where the hot tub sheet follows a soak.
Why are the ranges left blank?
Because a heated swim spa and a cold plunge want different things, and your manufacturer and the rules where you are set them. Write them in once at the top and read every row against them.
