PRO TIP
Rotate between two cartridges! While one is being deep-cleaned and dried, the other stays in the filter so your pool never goes without filtration. Dying the cartridge completely helps kill any remaining bacteria or algae spores.
Always follow label directions and safety guidance. Keep pool chemicals and accessories stored safely and out of reach of children.
