SpaGuard Brominating Tabs | Spa Bromine Tablets

From $33.99

Description

SpaGuard Brominating Tabs are slow-dissolving bromine tablets that deliver steady, hands-off sanitizing for your spa or hot tub. Like SpaGuard's other bromine products, they work as a one-step sanitizer and shock — controlling bacteria and clarifying the water to keep it pristine and clear — but in a convenient tablet form that releases bromine gradually over time.

That slow, controlled release is the appeal of tablets: placed in a floating dispenser or feeder, they maintain a consistent bromine level with far less day-to-day attention than measuring out granules. The tablets dissolve completely without leaving cloudy or insoluble residue, so you get clean, clear water and a sanitizer reserve that simply keeps working between check-ins. They can also be used as a super-oxidation (shock) treatment to clear the water of accumulated organic wastes.

Available in two sizes — a 1.5 lb container and a 4.5 lb container for owners who want a longer-lasting supply.

Pro Tip: Tabs vs. granules comes down to convenience. Brominating Tabs sit in a dispenser and release bromine slowly for hands-off, consistent sanitizing. SpaGuard Brominating Concentrate (granular) dissolves fast for precise, on-the-spot dosing and quick adjustments. Many owners use tabs for steady maintenance and keep the concentrate on hand for fine-tuning.

What's in the Box

Available in two sizes — choose your size at checkout:

  • 1 x SpaGuard Brominating Tabs — 1.5 lb (slow-dissolving tablets)
  • 1 x SpaGuard Brominating Tabs — 4.5 lb (slow-dissolving tablets)

Note: Both sizes are the identical formula — only the quantity differs. Use the tablets in a floating dispenser or feeder; never add tablets directly to the skimmer or place them on spa surfaces. Keep the container tightly sealed and store in a cool, dry place away from other chemicals.

Key Features
  • Slow-dissolving tablets — release bromine gradually for steady, consistent sanitizing.
  • One-step sanitizer and shock — controls bacteria and oxidizes in a single product.
  • Hands-off convenience — used in a dispenser, they maintain your bromine level with less daily effort.
  • No cloudy residue — dissolve completely for pristine, clear water.
  • Controls bacteria and clarifies — keeps water clean, safe, and clear.
  • Doubles as a super-oxidizer — can be used as a shock treatment to remove organic wastes.
How It Works

Bromine sanitizes by destroying bacteria and other microorganisms along with the organic contaminants bathers leave behind. SpaGuard Brominating Tabs are built on BCDMH (1-bromo-3-chloro-5,5-dimethylhydantoin), a compound that releases active bromine slowly as the tablet dissolves. That slow release is the key difference from granular products: instead of a quick dose you broadcast and adjust, the tablets meter out sanitizer steadily over hours, holding a consistent bromine residual in the water.

Placed in a floating dispenser or feeder, the tablets dissolve at a controlled rate that you can fine-tune with the dispenser's adjustable vents. The result is reliable, continuous sanitizing with less intervention. Used at a higher quantity, the same chemistry serves as a super-oxidation (shock) treatment, burning off accumulated organic wastes and refreshing the water.

Pro Tip: Keep your water balanced for the tablets to work their best — bromine performs across a wider pH range than chlorine, but staying in range still matters. Aim for a bromine residual of 3–6 ppm, pH of 7.2–7.8, and total alkalinity of 80–120 ppm.

Directions for Use

Start-Up

  1. Clean your spa surfaces, then back-flush and clean the filters.
  2. Ensure your spa's pH and alkalinity are within the proper ranges.
  3. Add 1 tsp of Brominating Tabs per 200 gallons of spa water (via your dispenser).
  4. Circulate the spa or hot tub water for 15 to 20 minutes.

Weekly Maintenance

  1. Using spa test strips, test your spa's water and adjust when needed.
  2. Ideal total alkalinity range: 80–120 ppm.
  3. Ideal pH range: 7.2–7.8.
  4. Ideal active bromine range: 3–6 ppm.

Super Oxidation

  1. Clean your spa surfaces, then back-flush and clean the filters.
  2. Ensure your spa's pH and alkalinity are within the proper ranges.
  3. Add 4 tsp per 200 gallons of spa water.
  4. Circulate the spa or hot tub water for 15 to 20 minutes.

Pro Tip: Always follow the dosing and dispenser directions printed on your container's label, which take precedence over any general guidance. Wait until your bromine level returns to a safe range before getting in — test before re-entry, especially after a super-oxidation treatment.

SpaGuard® Brand FAQs

What is SpaGuard?

SpaGuard is a professional-grade brand of spa and hot tub water care products — sanitizers, shocks, balancers, and water enhancers — formulated specifically for spas rather than adapted from pool chemicals. The line is designed to work together as a complete system for clean, clear, comfortable water.

Who makes SpaGuard?

SpaGuard is part of the BioGuard family of water care brands, a long-established name in pool and spa chemistry. That backing means the formulas are professionally developed and tested, with a reputation built over decades in the industry.

What water care systems does SpaGuard offer?

SpaGuard supports three complete care methods: a chlorine system, a bromine system, and the Soft Soak TRIO system. Each is a coordinated set of products, so you can match your routine to the sanitizer you prefer.

What makes SpaGuard different from generic spa chemicals?

SpaGuard products are engineered for the unique demands of hot, agitated, heavily used spa water, and they're built to work together as a system. That coordination delivers more reliable, repeatable results than mixing unrelated single products.

What is ALEX water testing?

ALEX is SpaGuard's exclusive computerized water-analysis tool used by its dealers. A quick water sample produces a precise read on your spa's chemistry and a tailored recommendation, taking the guesswork out of what to add and when.

Why buy SpaGuard from an authorized dealer?

SpaGuard dealers are trained on the brand's products and water-care technology, so you get expert advice alongside genuine product. They can run an ALEX analysis, troubleshoot issues, and recommend exactly what your water needs.

About SpaGuard®

Because the formulas are made for the unique demands of hot, agitated, heavily used spa water, owners get reliable, repeatable results with less guesswork. SpaGuard is also backed by a trained dealer network and ALEX water-analysis tools, so when a water issue does come up, there's an expert-tested path to fixing it. It's a trusted choice for anyone who wants clean, comfortable, sparkling water with a maintenance routine they can actually keep up with.
