A pool shock schedule is the planned frequency and timing of pool shock treatments throughout the swimming season.
Definition
A pool shock schedule is the planned frequency and timing of pool shock treatments throughout the swimming season.
Typical Values: Weekly maintenance: shock to 10 ppm FC; Emergency recovery: shock to 30 ppm FC
In Plain Language
A typical shock schedule: shock once per week on the same night (after the pump has run during the day for chemical distribution, and before the evening when UV is absent). Shock immediately after any heavy bather load, storm, or combined chlorine reading above 0.5 ppm. Use 1–2 lbs of cal-hypo per 10,000 gallons for weekly maintenance; higher doses for recovery situations.
Why It Matters
A regular shock schedule prevents chloramine accumulation and catches chemistry problems before they become emergencies.
Typical Values
Weekly maintenance: shock to 10 ppm FC; Emergency recovery: shock to 30 ppm FC
