Description
Pool Chemistry Pro is a professional water chemistry toolkit built for pool service technicians, certified pool operators, and serious pool owners. Get accurate, industry-standard calculations in seconds — no more guesswork, no more wasted chemicals.
WHAT YOU CAN DO
🧪 Langelier Saturation Index (LSI) Instantly evaluate corrosion and scaling potential from pH, temperature, calcium hardness, total alkalinity, cyanuric acid, and TDS. Color-coded results show exactly when water is balanced, scale-forming, or corrosive.
💧 Pool Volume Calculator Six pool shapes supported: rectangular, circular, oval, kidney, L-shaped, and freeform. Average-depth math handled automatically.
⚗️ Chemical Dosing (PRO) Precise dosage amounts for raising/lowering pH, free chlorine, total alkalinity, calcium hardness, and cyanuric acid. Supports liquid chlorine, cal hypo, dichlor, trichlor, soda ash, sodium bicarb, muriatic acid, dry acid, and calcium chloride.
🔄 Turnover Rate (PRO) Calculate how long it takes your pump and filter to circulate a full pool volume. Flag undersized systems before they cost you green water.
🧂 Salt Pool Manager (PRO) Salt level adjustments for chlorine generators, ppm targets, and cell maintenance reminders.
🧱 Filter Sizing (PRO) Recommend the right sand, cartridge, or DE filter based on pool volume and target turnover.
⚠️ Chlorine Neutralizer (PRO) Sodium thiosulfate dosing for over-chlorinated and shocked pools.
🏊 Pool Profiles Save unlimited pools (1 free) — name, client, volume, shape, salt status, and last service date. Perfect for pool service routes.
📊 Test History Every LSI calculation is saved with timestamps. Spot trends before they become problems.
