Sirona® Activate Granular
Product Overview
Sirona Activate Granular is the standard specification for spa owners who need to oxidize organic contaminants without the lingering scent of chlorine.
This 5 lbs. container of Sirona Activate Granular features 32.2% Potassium Peroxymonosulfate, a non-chlorine oxidizer that reliably handles the breakdown of ammonia and residual soaps. In our experience, it is a proven choice for clearing cloudy water in spas using bromine or mineral systems, as it reactivates spent bromine to maintain a 1-3 ppm residual without adding stabilizer or affecting calcium hardness.
Benefits & What Makes It Different
32.2% Potassium Peroxymonosulfate
This powerful non-chlorine oxidizer targets organic waste like oils and soaps without raising cyanuric acid levels or affecting calcium hardness in your spa.
Bromine Reactivation
When used with bromide salt solutions, it converts spent bromide back into active bromine to maintain a consistent 1-3ppm level for effective sanitation.
Fast-Acting Clarity
Formulated to eliminate ammonia and chloramines quickly, allowing users to return to the spa after just 15 minutes of circulation with the cover off.

When To Use This
Pro Tip
Spa owners in high-use environments often struggle with foaming; using this non-chlorine shock helps oxidize the residual soaps and body oils that cause those bubbles before they require a liquid defoamer. In regions with high evaporation rates, using a non-chlorine shock helps keep total dissolved solids lower than traditional chlorine shocks.
Common Questions & Instructions
How much Sirona Activate Granular do I need for a 500-gallon hot tub?
For general oxidation, apply 4 ounces (8 tablespoons) per 500 gallons, which follows the standard 2 ounces per 250 gallons ratio; if using the Sirona Bromide system, double that dose to 8 ounces.
Can I use this non-chlorine shock in a spa that uses chlorine?
Yes, Sirona Activate Granular is compatible with chlorine, bromine, ozone, and mineral purification systems, making it a versatile tool for removing contaminants without adding more sanitizer.
Does this product affect the pH or alkalinity of my spa water?
While primarily an oxidizer, it is important to test your water daily as the pH should be maintained between 7.2-7.8 to ensure the 3 ppm bromine residual remains effective and the water stays balanced.
