Buying Guide

Know which parameter to adjust

Test your pool water first so you choose alkalinity increasers, pH increasers, calcium hardness increasers, or shock products targeted to the imbalance

Match chemical type to use

Choose sodium bicarbonate for raising alkalinity, soda ash for raising pH, and calcium chloride for increasing hardness to avoid overshooting other parameters

Consider pack size and dosing

Larger bags lower cost per pound but require accurate measurement and storage; smaller bundles are convenient for occasional tuning

Prioritize granular vs tablet form

Granular powders dissolve faster and allow precise dosing, while tablets and measured cups can simplify routine maintenance

Safety and handling

Store chemicals in a cool, dry place, keep containers sealed, and always add chemicals to water, not water to chemicals, while wearing protective gear
