Overview

Nayoku mineral cartridge replacement is crafted to pair with the FROG @Ease in-Line SmartChlor system and is compatible with a range of popular spa models. This CYA-free 3-pack provides a mineral boost designed for spas up to 600 gallons, aiming to soften water and support a balanced water profile as part of your routine care.
