Trend Log
Hot Tub pH and Alkalinity Tracker
A tracker helps you spot drift patterns instead of reacting to one reading in isolation. The goal is recordkeeping, not replacing product labels or manufacturer guidance.
Minimal Logging Framework
- Date and time
- pH
- Alkalinity in ppm
- Current sanitizer mode
- Optional notes for soak load or unusual usage
Weekly Review Pattern
| Week | pH trend | Alkalinity trend | Action note |
|---|---|---|---|
| Week 1 | Stable | Slightly down | Keep logging |
| Week 2 | Rising | Stable | Re-check test method and usage changes |
| Week 3 | Stable | Stable | No change |
