Regal Brom Granules is a practical easy to use sanitizer for spa water. It rapidly and completely dissolves to provide effective bromine disinfection without cloudy or insoluble residue in the water. BROM GRANULES is a superoxidation treatment to rid spa water of organic waste such as perspiration, body oil, cosmetics that tend to cloud water. Directions for Use: 1. Maintain proper daily levels as determined by testing kit Free available chlorine between 3 – 5 ppm, pH 7.2 to 7.8, total alkalinity 100 – 120 ppm, and calcium hardness 150 – 200 ppm. 2. The filtration system should be maintained in order to ensure proper disinfection 3. Apply 6 g of BROM GRANULES per 1,000 L of spa water directly to bather-free spa water with circulation system operating. Test for available bromine and repeat above dosage at 15-20 minutes intervals until a residual of 3.0 – 5.0 ppm is reached. 4. Periodic superchlorination of spa water is recommended after heavy use or, once a week, in moderately used spas to remove organic waste. Apply 25 g of BROM GRANULES per 1,000 L of spa water as often as required. Bathers should not use spa until reading drops to 5.0 ppm. 5. Persistent foam formation, turbid or malodorous water are indicators of inadequate sanitizer levels. To correct such conditions, superoxidize spa water by adding 25 g of BROM GRANULES per 1,000 L of spa water. Maintain circulation at least 30 minutes and wait 4 hours before using. BROM GRANULES contains stabilizer (cyanuric acid) which will accumulate in spa water. Keep stabilizer within 30° 100 ppm range by dilution with fresh water. 6. For proper sanitation, spa must be completely drained periodically. The number of days between COMPLETE SPA DRAINAGE is equal to the volume of spa water in liters, divided by 10 times the maximum number of daily spa users. Refill spa with water and repeat DIRECTIONS FOR USE. Maximum spa water usage temperature is 40°C. Duration in spa water, at 40°C, should not exceed 15 minutes.
