Carbon dioxide is an alternative that is well worth considering.it doesn’t fit in the pool High alkalinity of source water (over 150mg/l as CaCO3) or calcium hardness (over 300mg/l as CaCO3) are also not suitable for leisure pools and spas as water features will drive them out of the water.
Does carbon dioxide reduce alkalinity?
change in Dissolved CO2 does not affect alkalinity, by definition, but does affect the pH of water. Therefore, stripping dissolved CO2 increases the pH of the water as it reduces the total inorganic carbon concentration but does not change the alkalinity concentration.
