Hot Tub Chlorine FAQs

Chlorinating granules are the most common choice for routine sanitizing. Leisure Time Spa 56, Sirona and SpaPure hot tub chlorine granules are all sold here, and the right size depends on how often you soak and how large your tub is.

Use chlorine labeled for spas and hot tubs. Pool chlorine is made for much larger volumes of water, so its form and dosing do not carry over to a hot tub. Pool owners can browse pool chlorine instead.

Hot tub chlorine keeps sanitizer levels up day to day, while shock is a heavier dose of oxidizer used after heavy use or when the water smells strong or looks dull. Browse hot tub shock to compare options.

Yes. FROG @ease uses SmartChlor chlorine cartridges, paired with a mineral cartridge, in floating or in-line systems. Check which one your tub uses before ordering.

In-stock orders ship within 12 business hours, and weekend orders ship Monday. Orders over $50 ship free, and every hot tub chlorine order has a 100% satisfaction guarantee.
