Each Scale-gon cartridge lasts around 6 months with average use and Salamander provides a free reminder service for end users so they don't forget to change the cartridge. Compared to polyphosphate tablets that are added to each wash, the Scale-gon approach costs over 60% less per wash.
Scale-gon provides long lasting protection for appliances and there is no chance of the user forgetting to add a tablet, so the protection is more consistent.
