Structured readings for every body of water, on whatever device is nearest — with the thresholds, corrective actions and monthly controller tests the code expects.
A therapy spa and a 50-metre competition pool do not share a safe range, and pretending otherwise is how a log becomes decorative. Thresholds are set per body of water, and the reading is judged against the pool it came from.
When a reading falls outside its range the entry does not simply save. It raises an alert and asks for the corrective action, so the record shows what was done about it — which is the part an inspector actually asks about.
Monthly MAHC controller interlock testing and the maintenance events nobody remembers six months later — backwashes, manual fills, media changes, chemical deliveries — live beside the chemistry they explain.
The same entries as the index — there is only one description of any feature on this site.

Monthly MAHC controller interlock testing, recorded on the schedule the code expects.
