Gunite and plaster have a high demand for acid because of the lime in the cement. And or high calcium make up water.

Your pool will naturally increase in pH due to swimmer's waste, sweat, urine, etc...
Keep your pH at 7.6-7.8, not 7.2. 7.2 pH is base upon the Langelier Index which was used for local water companies, but there's a world of difference between pools and how the water company treats your tap water. Good index but bad application for pools.
pH and Alkalinity/Acidity are functions of each other. pH's above 7.0 are considered alkaline and pH's below 7.0 are considered acidic. So reducing the alkalinity will by it's very nature reduce the pH of the pool.
When CaOCl2 is added to H20 the chlorate ions combine with the water to produce hypoclorous acid and hydroxide ions. The pools pH is subjected to alot of different vaiables the optimum pH for pools is between 7.2-7.8 so to lower pH add HCl or NaHSO4 or to raise pH add Na2CO3 or NaHCO3.
Increasing the temperature will cause the pH to decrease.
You will have to add an alkaline substance in order to get the kiddie pools water back to an acceptable PH level. Calcium carbonate would work to increase the PH.
The common name for HCl when used to lower pH in swimming pools is muriatic acid.

PH levels make sure water is not to acid.
I have never heard of it being used for that purpose and cant find any reference to it being used for that purpose. any acid would lower Ph however that does not mean that it wont have undesirable side effects.
The websites in Related links are useful. They have the information you need for soil and swimming pools.
A base or alkali affects the pH water by increasing it.
well if the PH is above 7 it is a base and if it is below it is an acid... if we swam in swimming pools that were acidic... that would be bad. i don't know about landfill sites...
Sulfuric acid is added in pools to control the pH of the water; many specialists don't recommend the use of H2SO4.
