Pool Chemical Dose Calculator

Exact amount of a specific product to move one water parameter (free chlorine, pH, total alkalinity, calcium hardness, CYA/stabilizer, or salt) from the current reading to a target, for a pool of the given volume in US gallons. Returns amount in oz/lb or fl oz/cups, side effects on other parameters, order of addition and wait time. Use product='auto' to get the standard product for that parameter. Typical requests: "how much shock do I add to a 15,000 gallon pool"; "how much liquid chlorine to add to pool"; "how much bleach to add to a 10000 gallon pool"; "how much chlorine to raise 1 ppm"; "how much muriatic acid to lower pH"; "how much acid to lower pH from 7.8 to 7.4"; "how much baking soda to raise alkalinity"; "how much soda ash to raise pH"; "how much stabilizer to add to pool"; "how much cyanuric acid for 20000 gallons"; "how much calcium chloride to add to pool"; "how much salt to add to salt water pool"; "how much salt for 15000 gallon pool"; "pool chemical calculator"; "pool chemical dosing"; "how much cal hypo to shock pool"; "how many pounds of shock per 10000 gallons"; "how much dry acid to lower pH"; "how much borax to raise pH"; "how much do pool chemicals cost per month"; "how to lower alkalinity in pool"; "how to raise pH in pool without raising alkalinity"; "how to lower CYA"; "how to lower calcium hardness"; "chlorine dose for green pool".

Free-chlorine minimum, target range, and shock (SLAM) level for the pool's stabilizer (CYA) level and sanitizer type (liquid/tablet chlorine or salt-water generator). Chlorine targets depend on CYA; never quote a fixed 1-3 ppm. Typical requests: "what should my free chlorine be"; "ideal chlorine level for pool"; "chlorine level for CYA 50"; "salt water pool chemistry"; "how much chlorine should a salt water pool have"; "free chlorine vs cyanuric acid ratio"; "FC CYA chart"; "what is shock level for my pool"; "SLAM level for CYA 40"; "how high should chlorine be to kill algae"; "minimum chlorine level swimming pool"; "chlorine too low what happens".

Step-by-step recovery plan for a specific pool problem (green or cloudy water, algae types, high CYA, chlorine that will not hold, pH drift, salt-cell flakes, chlorine smell), using the pool's volume and current readings. Returns the shock level, the first dose, what to test, and when to call a pro. Typical requests: "my pool is green what do I do"; "how to clear a green pool fast"; "cloudy pool water after shock"; "cloudy pool water fix"; "how to SLAM a pool"; "pool smells like chlorine and burns eyes"; "combined chlorine too high"; "CYA too high what now"; "yellow algae in pool"; "mustard algae treatment"; "black algae pool spots"; "chlorine disappears overnight"; "chlorine won't hold in pool"; "pH keeps rising in pool"; "white flakes coming out of pool returns"; "how long to clear a green pool"; "algaecide vs chlorine for green pool"; "pool turned green after rain"; "should I drain my pool high CYA".

Estimate pool volume in US gallons and liters from shape and dimensions in feet (length, width or diameter, shallow and deep depth). Use before any dosing when the user does not know their volume. Typical requests: "how many gallons is my pool"; "how many gallons in a 16x32 pool"; "pool volume calculator"; "how many gallons is a 24 foot round pool"; "how much water does my pool hold"; "how many litres in my pool"; "kidney shaped pool gallons"; "inground pool size in gallons"; "how to calculate pool volume"; "18x36 pool how many gallons"; "how many gallons is an above ground pool 15 ft".

Month-by-month pool care calendar for the user's climate (hot/warm/temperate/cold) and sanitizer, including opening and closing steps, test cadence and what to buy ahead of each season. Typical requests: "how to close a pool for winter"; "how to open a pool in spring"; "pool maintenance schedule weekly"; "pool care checklist"; "winterize pool chemicals"; "when to close pool in the northeast"; "pool maintenance in Florida year round"; "pool opening chemicals list"; "how often to test pool water"; "pool cover cost"; "automatic pool cover cost"; "how to maintain a pool for beginners".

Size a pump (GPM and horsepower class), filter (square feet by type), heater (BTU/hr for gas, heat pump class) and robotic cleaner class for a pool of the given volume, turnover, surface and climate. Returns recommended specs with buying links. Typical requests: "what size pump for my pool"; "what size pool filter do I need"; "cartridge filter size for 20000 gallon pool"; "sand filter size chart pool"; "what size pool heater do I need"; "heat pump vs gas heater pool"; "BTU pool heater calculator"; "which robot pool cleaner for my pool"; "best robotic pool cleaner for inground pool"; "variable speed pump size for pool"; "pool pump GPM calculator"; "turnover rate pool pump"; "pool equipment sizing"; "how big a filter for a 30000 gallon pool".

Calcite Saturation Index (CSI, the LSI adjusted for CYA) from pH, total alkalinity, calcium hardness, water temperature, CYA and salt/TDS. Tells whether water is scaling or corrosive for the pool surface and which parameter to move to fix it. Typical requests: "is my pool water balanced"; "langelier saturation index calculator"; "LSI pool calculator"; "CSI pool"; "pool scaling on tile"; "why is my pool water corrosive"; "calcium scale on salt cell"; "plaster etching pool chemistry"; "pool water balance calculator"; "ideal calcium hardness for plaster pool"; "alkalinity vs pH pool balance"; "pool water balance for vinyl liner"; "what should calcium hardness be in a salt pool".
