Pool Chemistry - Chlor

New: filter maintenance by pool or task type, add heater notes, and get corrected chlorine dose guidance for clearer water.

Chlor is the precision pool chemistry companion built for serious pool owners. Stop guessing - test smarter, dose accurately and swim in perfectly balanced water every time.

WHETHER YOU OWN A POOL, SPA OR HOT TUB Chlor tracks every body of water you manage. Log test results, calculate exact chemical doses and follow a smart maintenance schedule in one polished app.

ACCURATE CHEMICAL CALCULATORS Calculate free chlorine, pH, total alkalinity, CYA, calcium hardness, LSI, SLAM treatment, salt level and volume with clear targets.

SMART TEST LOGGING Log water tests quickly, see colour-coded status indicators and filter your full history by pool or hot tub.

CYA-ADJUSTED FREE CHLORINE TARGETS Chlor uses the scientifically correct FC:CYA ratio rather than the oversimplified 1-3 ppm most apps use.

MAINTENANCE SCHEDULE Create recurring tasks for skimming, filter cleaning and equipment checks. Chlor sorts them by overdue, due this week and upcoming.

MULTIPLE POOLS AND SPAS Each body of water gets its own test history, calculator context and maintenance schedule.

DESIGNED FOR ACCURACY The calculation engine is based on industry-standard formulae used by pool technicians and accounts for volume, current levels, targets and chemical concentration.

CHLOR PRO Unlock all 9 calculators, full test history, AI Pool Assistant, LSI and SLAM tools, and unlimited pools and spas.
