pH in conventional chemistry swimming pools is controlled by adding acid and alkali to the pool.  The amount of additive must be carefully calculated and test kits and ready reckoners are available. 


Most Australian pools drift alkaline almost continuously, due in part to alkali leaching from the pool surface finish, and partly due to the alkaline effect of the saltwater chlorinators used in ~92% of pools.  This means that acid must be added continually and the quantity of such acid can run to over 100 litres a year for new pool surface finishes.  This may sound surprising but pools have large surface areas that are often chemically active. 


It is, of course, highly undesirable and dangerous to have chemicals such as concentrated alkali and pool acid stored in a house, or outside in the area near your pool equipment. Regrettably there can be accidents and hazards, especially with young children.


With Pooled Energy’s Advanced Water Chemistry, most pools naturally settle within the desired pH operating range without the need to add acid. Very few pools need acid and, when they do, they only need very small quantities due to the logarithmic pH scale.
