The pH of calcium carbonate is around 9.8
7.7
Calcium carbonate is a base and hydrochloric acid is an acid but their combined pH depends on ther initial concentrations.
Aqueous solution of sodium carbonate has pH between 10-11

Calcium Carbonate :)
by adding calcium carbonate to raise the pH level.
Calcium Carbonate has a PH of about 9-10
Because calcium carbonate is a base, depending on the pH of the base, it will either increase or decrease the pH of the calcium carbonate very slightly. It will probably have little to no noticeable effects.
Carbonate will increase soil pH value, because it reacts with acid, but sulfate will not affect the pH.

Farmers use calcium carbonate to lowervthe pH.
Calcium carbonate is a base and hydrochloric acid is an acid but their combined pH depends on ther initial concentrations.
Aqueous solution of sodium carbonate has pH between 10-11
Over time soils on farms become acidic, calcium carbonate is added to fields to regulate the ph of the soil
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.
A 10% solution of calcium nitrate has a pH of about 6.0. Calcium nitrate is the primary source of water soluble calcium in hydroponics. Prolonged use in other growing media can result in a gradual increase in pH because the negatively charged nitrate ions are taken up faster than the positively charged calcium ions.
It raises the pH of the soil and reduces the availabilty of iron, magnesium and manganese.
