Pool Tools & Calculators
Free tools for every pool owner — pool volume calculator, chlorine dosing calculator, pool salt calculator, pool heater BTU calculator, pump turnover calculator, and pool water balance calculator.
🏊 Pool Volume Calculator
Find how many gallons your pool holds from its shape and dimensions — round, rectangular, or oval — in US gallons, cubic feet, and litres, the number every chemical and equipment decision starts from
🧪 Chlorine Dosing Calculator
Work out exactly how much chlorine to add to raise your free chlorine to target — for liquid chlorine, cal-hypo, dichlor, or trichlor — based on your pool volume and current reading
🌊 Pool Salt Calculator
Calculate how much salt to add to reach your chlorine generator's ideal salinity — results in pounds, kilograms, and 40-lb bags from your volume and current level
♨️ Pool Heater BTU Calculator
Estimate the heat energy needed to warm your pool by a given number of degrees, and how many hours a heater of a certain output will take — the key to sizing a heater and planning warm-up time
🔵 Pump Turnover Calculator
Get the pump flow rate you need for a target turnover, or the hours your pump takes to circulate the whole pool once — so you can size a pump or set your daily run time
⚗️ Pool Water Balance Calculator
Check whether your water is balanced, corrosive, or scale-forming with the Langelier Saturation Index — from your pH, alkalinity, calcium hardness, temperature, and TDS
Pools & Water Museum
Dive into an immersive museum of pools and water — the pool types from the backyard above-ground to Olympic lanes and infinity edges, the pumps, filters, and cleaners that keep them clear, the chemistry of balanced water, and the backyard and aquatic life around them, each in its own gallery, so you can get to know the story behind every pool: how it works, what keeps it swimmable, and the craft of a great backyard oasis.
