Enter your pool volume (or dimensions) and your latest test readings and get the exact amount of the product you own to add: liquid chlorine, cal-hypo, dichlor, trichlor, muriatic acid, dry acid, soda ash, borax, baking soda, calcium chloride, stabilizer or salt, with the order of addition, side effects on other readings and when to retest.
Typical requests: how much chlorine to add to my pool, how much shock for a 15,000 gallon pool, free chlorine target for my CYA level, salt pool chlorine level, how to lower pool alkalinity, how much muriatic acid to lower pH, raise pool pH with soda ash, how many gallons is my pool, is my pool water balanced (CSI), why is my pool cloudy, green pool recovery plan, high CYA fix, what size pump or filter for my pool, pool opening and closing schedule.
Computes free-chlorine targets from your CYA level (chlorine and salt pools), the Calcite Saturation Index for scaling or corrosion, step-by-step recovery plans for green, cloudy, algae and high-CYA water, pump, filter, heater and robot sizing, and a seasonal care calendar for your climate. Every result is shown as a card with the dose, the steps and the matching test kit or chemical to buy. All math is the chemistry mass balance used by pool professionals. No account needed.
