Buying Guide

Choose the right salt form

Pellets, crystals (solar), and blocks dissolve differently; pellets often reduce bridging while solar salt is granular and may suit older tanks

Match bag weight to your storage

Common sizes here are 40–50 lb; pick a bag weight you can carry and store safely to avoid moisture exposure

Look for rust or iron defense

If your water has iron, select salts labeled for rust defense or iron removal to help protect resin and improve taste

Check purity and additives

Higher-purity salts have fewer insolubles; some formulas add rust inhibitors or conditioners—choose based on your system needs

Consider brand and supply consistency

Established suppliers and consistent bag sizes simplify maintenance planning and reduce mismatched material risks
