ClearSpa quarterly Water Insight report

Each quarter ClearSpa publishes an anonymised, aggregated report of the hot-tub water chemistry readings customers log in Water Insight & Tracking. Figures are frozen at publication, drawn from hot tubs only, capped at one reading per customer per day, and withheld below minimum sample thresholds so no individual customer can ever be identified. Journalists and researchers may quote the figures with credit to ClearSpa.

• Anonymised aggregates from real ClearSpa customer hot-tub readings
• Average pH and share of readings in the ideal 7.2-7.6 band
• Per-parameter averages and in-range rates where the sample is large enough
• The parameter owners most often get wrong each quarter
• Published methodology, limitations and sample sizes with every figure
• Immutable published figures - quotable and reproducible
