Swimming pool calculatorsCalculating the volume of a swimming pool. Adding sodium bicarbonate to increase total alkalinity. Adding hydrochloric/muriatic acid to reduce total alkalinity. Adding dry acid (sodium bisulphate) to reduce total alkalinity. Adding calcium chloride to increase calcium hardness. Adding stabiliser (cyanuric acid). Adding soda ash (sodium carbonate) to increase pH.
POOL VOLUME CALCULATOR Find the shape of your swimming pool and fill in the measurements below it to calculate the volume of water the swimming pool holds.
CONVERT GALLONS to LITRES To convert gallons to litres, enter the amount of gallons and choose which kind of gallons you are working with.
CONVERT LITRES to GALLONS To convert litres to gallons, enter the volume in litres.
TOTAL ALKALINITY : (80120 ppm) To calculate how much sodium bicarbonate your swimming pool requires to increase the total alkalinity, choose the increase you want and enter the volume of your pool.
TOTAL ALKALINITY : (80120 ppm) To calculate how much hydrochloric acid (muriatic acid) your swimming pool requires to decrease the total alkalinity, choose the reduction you want and enter the volume of your swimming pool.
TOTAL ALKALINITY : (80120 ppm) To calculate how much dry acid (sodium bisulphate) your swimming pool requires to decrease the total alkalinity, choose the reduction you want and enter the volume of your swimming pool.
CALCIUM HARDNESS : (250350 ppm) To calculate how much calcium chloride your swimming pool requires to increase the calcium hardness, choose the increase you want and enter the volume of your swimming pool.
STABILISER : (3080 ppm) To calculate how much stabiliser (cyanuric acid) your swimming pool requires to increase the stabiliser level, choose the increase you want and enter the volume of your swimming pool.
SODA ASH (pH 7.07.6) To calculate how much soda ash (sodium carbonate) your swimming pool requires to increase the pH level, choose the increase you want and enter the volume of your swimming pool.
