Description
Fast-Dissolving 2-in-1 Hot Tub Sanitizer and Shock
Sirona™ Spa Care Chlorinating Granules are a concentrated 2-in-1 treatment made for spas and hot tubs. They sanitize and shock in one product, dissolving quickly to keep water clean, clear and ready when you are.
The 99% sodium dichlor formula has a near-neutral pH, so it has minimal effect on water balance. The 4 lb container is the value size for frequent soakers.
One Product for Daily Sanitizing and Weekly Shock
Use small daily doses to keep free chlorine at 2 to 3 ppm, then a larger weekly dose to shock away odors and organic contaminants. One container handles both jobs.
That keeps your spa care routine simple and your shelf uncluttered.
Dissolves Fast, Works Fast
The fine granules dissolve almost instantly in hot water and start working right away. Most spas are ready again within 15 to 30 minutes, once chlorine returns to 3 ppm or below.
Just broadcast the granules evenly over the water surface.
Gentle on Water Balance
With a near-neutral pH, dichlor has minimal impact on your spa's pH, making balance easier to maintain.
Test 2 to 3 times a week and keep pH between 7.2 and 7.8.
