PoolDose - Pool Chemistry Calc

Turn your latest water test into a clear dose plan. PoolDose is an offline pool and spa chemistry calculator with saved pool profiles, product settings, and a reading log. A GUIDED DOSE PLAN Confirm your pool volume and products, enter your current test readings, review your targets, and calculate estimated product amounts. Targets start at your current readings, so you choose what to change. Routine free-chlorine guidance is based on stabilizer (CYA); shock-treatment targets are a separate choice. REVIEW BEFORE YOU ADD Calculate supported adjustments for free chlorine, pH, total alkalinity, calcium hardness, stabilizer (cyanuric acid), and salt. Dose cards show product strengths, estimated secondary effects, directions, and warnings. After making an addition, tap “Mark as added” to save it in your reading history. Dilution guidance is shown separately from chemical additions. Salt-water generator output is not calculated. KEEP YOUR WATER HISTORY Save water tests, review 30-, 90-, or 365-day trend charts for each pool, and export your reading log as CSV. You can explicitly import your latest saved test into a new dose plan and review it before continuing. CHECK WATER BALANCE Use the Langelier Saturation Index (LSI) to estimate scaling or corrosion tendency. Review the balance gauge, suggested adjustment, and chlorine/stabilizer reference table. SAVE YOUR POOLS AND PRODUCTS Keep multiple pool and spa profiles with volume, surface, sanitizer, and product strengths. Estimate volume for rectangular, round, oval, kidney, or freeform pools using feet and inches or meters. Choose supported chlorine, acid, base, and calcium products in each pool’s settings. Pay once. No subscription, account, ads, or locked reading history. Calculations and saved records work offline. PoolDose provides estimated chemical amounts based on standard pool-chemistry formulas and the concentrations you enter. Always read and follow product labels, add chemicals one at a time, never mix chemicals, and retest before adding more. Results depend on accurate volume and test readings.
