Out-of-range protocol: If any parameter falls into the danger zone, record the corrective action taken in the "notes" column with date/time/initials. Don't open plunge to users until parameters are back in target range and a recheck has been logged. Free Chlorine below 1 ppm: close plunge immediately, add sanitizer, wait minimum 2 hours, retest, reopen only when ≥3 ppm.
