Common Questions & Instructions
How does Sirona Spa Up affect total alkalinity and pH in my hot tub?
Sirona Spa Up delivers 100% Sodium Bicarbonate, which primarily raises total alkalinity into the ideal 80–120 ppm window while gently nudging pH toward the target 7.2–7.6 range for optimal bather comfort.
Can I use Sirona Spa Up in a spa sanitized with bromine?
Yes, this 2 lbs. formula is fully compatible with bromine, traditional chlorine, ozone, and saltwater systems, distributing quickly without neutralizing active sanitizer residuals.
How long should I wait to soak after adding Sirona Spa Up?
Run your spa jets for 15 to 20 minutes with the cover off after adding the granules, then retest water chemistry before bathers enter.
