Buying Guide

Match chemical form to your system

Choose tablets for dispensers or granules for manual dosing; brominating tablets suit spas while soda ash is used to raise alkalinity and pH

Check active ingredient and concentration

Look for the listed active chemical (e.g., sodium carbonate for pH adjustment) to ensure compatibility with your current treatment plan

Prioritize ease of dosing

Pre-measured tablets or clearly labeled weight bags simplify consistent treatment and reduce dosing errors

Consider storage and handling needs

Powders and granules require dry storage and careful measuring, while tablets often come in sealed containers that resist moisture

Evaluate ancillary accessories

Items like water tube cover weights help protect treated water and reduce contamination, complementing your chemical regimen
