Buying Guide

Match the chemical to the problem

Use sodium bicarbonate for low alkalinity, soda ash for low pH, calcium chloride for low hardness, and shock products to oxidize contaminants

Check active ingredients

Confirm whether a product lists sodium bicarbonate, soda ash, calcium chloride, or stabilized shock to ensure compatibility with your pool system

Size and dosing convenience

Choose bag weights or bundled sizes that fit your pool volume and look for measured scoops or clear dosing instructions for easier application

Consider pool type and equipment

Use lower-alkalinity adjustments for vinyl pools and avoid calcium increasers with soft-water systems or sensitive heaters

Safety and handling

Store chemicals dry and labeled, add chemicals to water (never water to chemicals), and wear gloves and eye protection when dosing
