🏊 Pool Calculator
IMPORTANT INFORMATION
Pool Calculator - Estimation Tool Only
This calculator estimates pool volume and chemical requirements based on dimensions and water chemistry.
⚠️ POOL MAINTENANCE DISCLAIMER ⚠️
This calculator provides estimates only. Actual requirements depend on: precise pool measurements, water temperature, bather load, sunlight exposure, filtration system efficiency, water source chemistry, specific chemical product concentrations, local regulations, and environmental factors. Results are estimates for reference only. CRITICAL: Always test water with reliable test kits before adding chemicals. Follow manufacturer instructions for all pool chemicals. Never mix different chemicals directly. Store chemicals safely away from children and pets. Consult pool professionals for persistent water quality issues. Users assume full responsibility for chemical safety and water balance.
⚠️ CHEMICAL SAFETY NOTICE
Pool chemicals can be hazardous if not handled properly. Always: wear protective gloves and eyewear, add chemicals to water (never water to chemicals), store in cool dry place away from direct sunlight, keep out of reach of children, follow all label instructions precisely, never mix different types of chlorine or other chemicals, pre-dissolve granular chemicals before adding to pool, run circulation system when adding chemicals, wait appropriate time before swimming after chemical addition.
📋 CALCULATION BASIS
Volume calculations: Rectangular = L×W×D×7.5, Round = π×R²×D×7.5, Oval = L×W×D×5.9, Kidney = (A+B)×L×D×3.38, Freeform = L×W×D×7.0 (approximate). Chlorine adjustment: Gallons × (Target - Current) ÷ 120,000 = lbs of chlorine needed (for standard 65% calcium hypochlorite). Standard chlorine range: 1-3 ppm for residential pools. Shock treatment: 10x normal level. Always verify calculations with professional testing. All formulas are industry-standard approximations.
