HTH Spa Bromine Multi-Action 4 tablets are high-efficiency 20 g bromine tablets designed for continuous sanitization of spas, hot tubs and whirlpools.
Their multi-action formula provides disinfection, algae prevention, water clarification and filtration support in a single, easy-to-use product.

The tablets dissolve slowly and evenly, ensuring long-lasting protection and stable bromine levels, even in demanding hot-water conditions with high pH.

Key Features

• 4-in-1 multi-action formula: disinfects, controls algae, clarifies water, enhances filtration

• 20 g slow-dissolving tablets for long-lasting effect

• Over 96% active ingredient for powerful sanitation

• Effective at high temperatures and high pH

• Low odor and more comfortable than chlorine in warm water

• Compatible with all types of spas and dosing systems

• Leaves no residue and supports consistently clear water

What the Tablets Do

1) Disinfection

Eliminates bacteria, viruses and fungi to maintain hygienic spa water.

2) Algae Prevention

Reduces algae growth and prevents their reappearance.

3) Water Clarification

Helps collect suspended particles, making filtration more efficient.

4) Continuous Protection

Slow dissolution ensures a stable disinfectant level with minimal maintenance.

⚠️ IMPORTANT – Bromine By-Products & Effects to Be Aware Of

Bromine naturally forms several by-products during water disinfection. These are not dangerous, but users should know how they behave and how to manage them.

1) Bromamines – normal, but should be controlled

Bromine reacts with sweat, cosmetics, body oils and urea, forming bromamines.

They are:
✔ milder than chloramines
✔ less irritating
✔ much lower odor

If bromamines accumulate, you may notice:

• a light chemical smell

• mild skin sensitivity (in rare cases)

• reduced disinfection efficiency

How to reduce bromamines:

• clean filters regularly

• use non-chlorine shock once per week

• shower before using the spa

2) Bromides (Br⁻) – safe, but may accumulate

As bromine works, it converts into bromide ions. These are harmless, but over time they can:

• slightly reduce sanitation efficiency

• increase tablet consumption

• create a “heavier” water feel

Recommendation:

Change the spa water every 2–3 months.

3) Organic residues – caused by users, not bromine

Residues in spa water typically come from:

• lotions

• oils

• cosmetics

• sweat

• dead skin particles

These can overload the filter and form a light film on the surface.

To avoid this:

• rinse or shower before spa use

• clean filters frequently

• perform periodic system flushing

4) Over-dosing bromine

Excessive bromine levels may cause:

• dry skin

• mild eye or nose irritation

• stronger chemical smell

• faster wear of metal components (rare cases)

Optimal bromine level: 3–5 ppm

Water Testing Recommendation

To maintain safe and stable spa water:

• check bromine levels regularly

• maintain pH between 7.2–7.8

• monitor alkalinity

• refresh water periodically to avoid bromide buildup

Directions for Use

Place the tablets in a floating dispenser or the designated dosing compartment.
Never place tablets directly on acrylic surfaces.
