Why We Don’t Use Bromine in Hot Tub Water Care

DATE: 5/5/2025

When it comes to keeping your hot tub clean and safe, not all sanitizers are created equal. At HydroPro Hot Tub Service, we specialize in professional spa maintenance and repair in Queen Creek, Chandler, Gilbert, Mesa, and the East Valley — and one of the first things we advise new customers is to avoid bromine in their spa.

The Problem With Bromine

Bromine is commonly marketed as an alternative to chlorine for spas, but what many don’t realize is that bromine is significantly more corrosive than chlorine — especially over time. It can:

  • Eat away at seals and internal components

  • Cause pH instability, making balancing more difficult

  • Break down spa covers and jets faster

You’ll find many service professionals, including us, replacing pumps, gaskets, and plumbing that were exposed to bromine-based systems far more often than chlorine-treated spas.

According to SpaDepot, bromine has a pH of 4.0–4.5, which makes it far more acidic and destabilizing to water chemistry than properly managed dichlor chlorine, which has a neutral pH impact when used correctly.

Why Dichlor Chlorine Is Better

We only use and recommend sodium dichlor, a stabilized form of chlorine that:

  • Maintains balanced water chemistry

  • Is gentler on components and spa shells

  • Works effectively in both cold and hot water

  • Is compatible with systems like the Frog @ease floating sanitizer system we include in all HydroCare Plan services

For anyone receiving bi-weekly hot tub service in Mesa, Gilbert, or Queen Creek, this choice helps keep your hot tub clean without risking premature wear on parts.
