Spa pool / hot tub operation log
A daily operating log for spa pools and hot tubs under HSG282, recording disinfectant residual, pH, temperature, bather load and dilution/dump so water quality is kept under continuous control.

How to use it
- Test and record disinfectant residual, pH and temperature several times a day as set out in HSG282 and your operating procedure.
- Record approximate bather load and any dilution, dump or filter backwash carried out to maintain water quality.
- Act on and log any reading outside your control range - dose, dilute or close the spa as needed.
- Treat the recommended residual/pH ranges and microbiological sampling intervals as per HSG282 and your own plan; the values shown are illustrative readings, not targets.
