Description
20 g bromine tablets, slow-dissolving, for disinfecting pool and spa water.
Free from chlorine odor, with high tolerance to pH variations.
Product with high disinfecting power and highly oxidizing.
Properties
Appearance: Solid tablets weighing 20 g.
Color: White.
pH (saturated solution): 4,6.
Solubility (25ºC): 0.15 g/100 cc water.
Available bromine content: 61%.
Composition: 1-Bromo-3-Chloro-5,5-Dimethylhydantoin.
Characteristics
- Effective disinfection against bacteria, algae, and fungi; its disinfecting power is not dependent on pH within a range of 7 to 8.
- High disinfection power, allowing it to destroy all organic matter present in the water.
- The combination of bromine with organic amines produces compounds called bromamines (NHBr2), which, unlike chloramines (the combination of chlorine with organic amines), do not reduce the effectiveness of bromine disinfection.
- Bromamines do not cause eye irritation or unpleasant odors.
- It is dosed through a tablet feeder, thereby providing the correct disinfection level, protecting bathers and preventing excessive product consumption.
- For shock treatment, Oximines is recommended. This treatment consists of a chlorine-free shock product specially formulated for use in bromine-treated pools or spas.
Reaction of bromine tablets with water
1. Bromine tablets + Water = DMH + Hypochlorous Acid + Hypobromous Acid
When bromine tablets dissolve in water, hypochlorous acid (active chlorine) and hypobromous acid (active bromine) are formed.
2. Hypobromous acid reacts with hypochlorous acid, in turn forming bromide ions.
3. This bromide ion reacts with hypochlorous acid, forming hypobromous acid again.

The disinfection resulting from the reaction of Bromine Tablets with water is hypobromous acid. Hypochlorous acid acts as a bromine regeneration agent.
Dosage and directions for use
When your pool's pH is adjusted between 7.2 and 7.6, fill the tablet feeder with bromine tablets, then adjust the feeder to obtain the desired Residential Bromine level.
The recommended Residential Bromine levels vary depending on the type of pool, as follows:
- Private Pools 1.0–3.0 ppm.
- Private Spas 2.0–4.0 ppm.
- Public Pools 3.0–5.0 ppm.
- Public Spas 4.0–6.0 ppm.
You can easily measure this value with a bromine and pH test kit.
