Common Questions & Instructions
How do I dose Sirona Brominating Granular for my hot tub?
For fresh fills or start-up, add 1.5 teaspoons (7.5 grams) per 300 gallons of water with the circulation running. For a periodic shock treatment, add 6 teaspoons (30 grams) per 300 gallons.
Why is bromine preferred over standard chlorine in hot tubs?
Bromine remains stable and effective at higher water temperatures, producing fewer odors and significantly less eye irritation than standard chlorine.
Does this product affect pH and alkalinity levels?
The granular formula is near pH neutral, meaning it sanitizes effectively without causing substantial drift outside the ideal pH 7.2–7.6 range.
