Common Questions & Instructions
Can I use Sirona Replenish in a bromine spa?
Yes, Sirona Replenish is fully compatible with bromine systems as well as chlorine and mineral systems, effectively oxidizing spent bromides back into active sanitizer.
How much Sirona Replenish do I dose for regular hot tub maintenance?
For routine spa maintenance, broadcast approximately 1.5 ounces per 250 gallons directly into circulating water with jets running. Maintain total alkalinity at 80–120 ppm and pH at 7.2–7.6.
Does Sirona Replenish raise cyanuric acid (CYA) levels?
Because it contains 15% Sodium dichloro-s-triazinetrione, it contributes a small amount of stabilizer over time, so monitor CYA to keep it within the recommended 30–50 ppm range.
