Summer High Chlorine Demand
In peak summer, most pools need more frequent chlorine additions because UV, heat, and swimmer load all increase the rate at which free chlorine is consumed.
Checklist
- Test FC at least daily during heavy use weeks
- Run pump long enough for full turnover
- Keep pH in range so chlorine stays effective
- Brush after parties; shock if CC rises
- Check CYA isn’t excessive—see high CYA issues
Step-by-step sections
Morning: quick FC/pH test. Evening: second check on busy weekends. Weekly: full panel including alkalinity.
Heat detail: temperature and chlorine.
Common mistakes
- Same winter dosing schedule in July
- Ignoring stabilizer context on sunny pools
- Shocking blindly without knowing CYA and FC
