SpaPure Brominating Tabs | Slow-Release Spa Bromine

• 1 x SpaPure Brominating Tabs (1.5 lb resealable container, tablets)

• Concentrated bromine sanitizer — 98% BCDMH for effective, continuous hot tub sanitation
• Low odor — the sanitizing power of chlorine without the chlorine smell
• Gentler on skin and eyes — a milder soak than chlorine in hot, agitated spa water
• Slow, even dissolving — releases gradually for a steady residual between uses
• Fits most feeders and floaters — drops into standard spa floating dispensers and erosion feeders
• Faster startup residual — builds a protective bromine level quickly once the water is seeded

As water flows past the tabs in your feeder, the BCDMH dissolves and releases active bromine that sanitizes the water on contact. The goal is to hold a 2–4 ppm bromine residual at all times, which the feeder maintains automatically as long as it has tabs in it.

Bromine has a useful trick that chlorine doesn't: when it's "used up," it doesn't simply vanish — it converts to spent bromide that stays in the water. Adding an oxidizing shock reactivates that bromide back into fresh, active bromine, so shocking your spa effectively recharges your sanitizer rather than just cleaning the water. That's why a bromide bank plus regular shocking makes bromine so efficient in a hot tub.

Pro Tip: Don't over-feed. Start with the feeder dial set low and check your bromine with test strips after a day — it's easy to crank a floater wide open and end up with bromine too high to soak. Dial it up gradually until you're holding 2–4 ppm, and never re-enter the spa until the reading is at or below 4 ppm.

Never mix this product with other chemicals in the same container. On a fresh fill, balance the water and seed the bromide bank before relying on the tabs.

1. Adjust spa water pH to 7.2–7.6 and balance total alkalinity.
2. On a freshly filled spa, add sodium bromide per its label to establish a 2–4 ppm bromine residual before first using the tabs.
3. Load the tabs into your floater or feeder and set the dispenser to maintain a 2–4 ppm bromine residual.
4. Check the feeder regularly to confirm it's still dispensing; add more tabs when it runs low.
5. Test bromine often with a reliable test kit and adjust the feeder as needed.
6. Change spa water every 60–90 days for residential use (commercial spas every 3–5 days).

Pro Tip: Lift the floater out of the water (or close the feeder) before anyone gets in if your bromine tends to run high — and always confirm the residual is 4 ppm or lower before re-entering. A 30-second test saves you from a too-strong soak.

• Target Level: 2–4 ppm bromine (residential)
• Dispensing: Requires a spa floater or erosion feeder
• Startup: Establish a bromide bank with sodium bromide on each fresh fill
• Water Change: Every 60–90 days residential; 3–5 days commercial
• System: For bromine-method spas (not for chlorine routines)
• Shipping: Ground shipping only (ships via UPS Ground; classified as a regulated brominating product)

These tabs are the primary sanitizer for spas run on a bromine program, and they require a floater or erosion feeder to dispense properly — they aren't meant to be tossed loose into the water.

They work as a system with sodium bromide (to establish the bromide bank at startup), an oxidizing shock (to reactivate bromide and clear bather waste), your pH and alkalinity balancers (kept in range so the bromine performs), and bromine test strips to confirm the 2–4 ppm target. Because they're a bromine product, they are not used alongside a chlorine sanitizing routine.
