$/lb chlorine is the price divided by the pounds of available chlorine in the container, so a 50 lb bucket, a 10% jug and a 12.5% jug all compare fairly.How it's calculated.
Is there a difference besides price?
Plain 3" tablets from any brand are trichlor, labelled around 99% trichloro-s-triazinetrione and 90% available chlorine, so they sanitize the same way and add the same stabilizer. Differences that do matter: multi-action lines (less chlorine per pound, plus clarifier or algaecide), individually wrapped tabs (easier handling, higher price), and how fast a brand's tablets dissolve in your feeder. Check the label before you compare.
