Spa & Hot Tub Bromine Generator & Brominator Systems

Maintain pristine, soft-feeling spa water with a dedicated bromine generator or brominator designed for hot tubs and spas. Bromine is the preferred sanitizer for spas due to its stability at high temperatures and reduced skin irritation compared to chlorine. PST Pool Supplies stocks electronic bromine generators, inline brominators, and floating tablet feeders from BluWater Technology, Gecko, GAME, and CMP — covering everything from automated in-line systems to simple floating brominators.

The BluWater Blu Fusion bromine generators represent the latest generation of electronic bromine generation — dual voltage (115V/230V), with topside control options and intelligent dosing that eliminates the dry skin, pungent odor, and tablet residue associated with traditional bromine feeder systems. The Gecko in.Clear bromine generator is a popular OEM-integrated choice for Gecko-equipped spas, offering seamless control through the spa's native topside panel. For simpler installations, the CMP Top Load Brominator accepts 1" bromine tablets directly and connects inline with spa plumbing for consistent, passive sanitization. The GAME Derby Duck and Derby Dolphin floating brominators are hassle-free floaters for smaller spas and above-ground applications — no plumbing required. For comprehensive sanitization systems, also see our pool and spa automation collection. For official BluWater documentation, visit BluWater Technology's website.

Bromine generators work by electrolyzing sodium bromide (NaBr) added to the spa water, continuously producing bromine on demand without the need for manual tablet additions. This method produces softer, more stable water chemistry with less pH fluctuation. All electronic generators in this collection require proper sodium bromide priming before first use — follow manufacturer startup instructions carefully. Inline brominators and floating feeders use pre-formed 1" bromine tablets and require monitoring and adjustment of bromine levels to maintain the recommended 3–5 ppm range in spas. For replacement parts and accessories, see our spa parts collection. Bromine safety and handling guidance is available from the U.S. EPA Safer Choice program.

Shop bromine generators and brominators and keep your spa water crystal clear, soft, and perfectly sanitized all year round.
