Description

Leisure Time Bromine Tablets (Brom Tabs) are slow-dissolving sanitizing tablets formulated specifically for spas and hot tubs. Active chemistry: Dantabrom (bromochloro-dimethylhydantoin) — a proprietary BCDMH-class compound that delivers 10% more active sanitizer than standard BCDMH tablets and 2.5x the solubility, making it ideally suited for the floating feeders and in-line dispensers used in residential spas. The tablets are low-odor, low-dust, and produce no harsh chlorine smell — making bromine the preferred sanitizer for owners with sensitive skin, eyes, or anyone who simply doesn’t want their hot tub to smell like a pool.

Bromine and chlorine both kill bacteria and viruses effectively, but they behave very differently in hot water. Chlorine works in a narrow pH window (7.4–7.8) and loses potency quickly as pH drifts upward — at pH 8.0, chlorine is operating at less than half its strength. Bromine, on the other hand, stays effective across a much wider pH range (7.0 to 8.4), so it tolerates the natural pH drift of spa water without leaving you under-sanitized. Bromine also doesn’t produce the “chlorine smell” most people associate with hot tubs, and its sanitizing byproducts (bromamines) remain active sanitizers rather than becoming irritating waste products like chloramines.

One 2.2 lb bottle of Brom Tabs provides several months of continuous sanitation for a typical residential spa when fed through a standard floating dispenser. Combined with the Reserve sodium bromide “bromide bank” at fresh fill and periodic shock from Renew, Brom Tabs form the foundation of one of the most comfortable, low-maintenance sanitizer programs available for residential hot tubs.

Pro Tip: Brom Tabs are designed for continuous slow-dissolve delivery through a floating dispenser or in-line feeder — not for direct addition to spa water. Dropping tablets directly into the tub causes localized over-bromination and can permanently stain or bleach acrylic shells and pillows. If you don’t already own a floating bromine dispenser, get one before you open the bottle — they’re inexpensive and they’re not optional.
