SpaGuard Brominating Concentrate sanitizes spa and hot tub water using a granular bromine formula that dissolves quickly and leaves no residual chlorine odor. It kills bacteria and controls contaminants while staying pH neutral, so it won't throw off your water balance with every dose.

Key Features

• 82.5% sodium dichloro-s-triazinetrione combined with 14.7% sodium bromide delivers effective bromine sanitization in granular form
• pH neutral formula — won't drive pH up or down, reducing the need for corrective balancing after dosing
• Compatible with ozone systems and mineral sanitizers, making it a flexible choice for most spa setups

For routine maintenance, dose 1 tsp per 200 gallons to maintain 3–6 ppm bromine. For super-oxidation or algae control, increase to 4 tsp per 200 gallons. Test water before dosing and retest after 15–20 minutes with the jets running to confirm sanitizer levels.

Always pre-dissolve granules in a bucket of water before adding to the spa. Do not add directly to the skimmer or mix with other chemicals. Keep bromine levels within the 3–6 ppm range — levels above 10 ppm can cause skin and eye irritation.
