# Calculator

## Swimming pool calculatorsCalculating the volume of a swimming pool/spa. Adding sodium bicarbonate to increase total Adding hydrochloric/muriatic acid to reduce total alkalinity. Adding dry acid (sodium bisulphate) to reduce total Adding calcium chloride to increase calcium 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
