PoolChem: Pool Water Care

PoolChem helps pool owners turn water-test readings into a clear care plan.

Set up a pool profile with the water volume, sanitizer type, surface, and target-range preset. Log pH, free chlorine, total chlorine, total alkalinity, cyanuric acid, calcium hardness, water temperature, and notes from each test.

The water dashboard brings the latest results together in one place. A five-part balance ring and individual range statuses show which readings are on target and which need attention.

When a reading needs correction, the dosing calculator estimates an amount using the pool's actual water volume and current chemistry. Each recommendation explains the target change, names the common treatment product used for the estimate, and includes handling guidance.

PoolChem also keeps a dated test history with parameter trend charts, so gradual changes are easier to spot.

Key features:
- Pool profiles with liters or US gallons
- Chlorine and salt-water target presets
- Guided logging for seven water-test measurements
- Water-balance score and five-parameter status ring
- Volume-aware chemical dose estimates
- Dated history with chemistry trend charts
- Practical target ranges, testing rhythm, and chemical-safety guide

Pool profiles and test history are stored on the device. No account is required. Optional feedback sends only the message and reply email you choose to provide, plus basic app and device details, through Web3Forms.

Dose estimates use common product strengths. Always check the product label, add one chemical at a time, keep the pump running, and retest before adding another dose. PoolChem supports routine recordkeeping and does not replace product instructions, professional pool service, or local public-health guidance.
