Primary purpose: to raise calcium hardness levels which is crucial for protecting your equipment and maintaining clear water.
Prevents Equipment Corrosion: Soft water (low calcium) is "aggressive" and will leach minerals from metal and stone. The product protects your pump and plumbing from rust and degradation.
Controls Foaming: Low calcium levels often cause excessive, persistent foam on the water's surface. Adding a booster helps stabilize the water to keep it clear and calm.
Standard Dosage: 1 oz of product to 500 gallons of water will raise the hardness by approximately 7–10 ppm.
Recommended calcium hardness between 150-400 ppm.
Active ingredient: Calcium Chloride

Frequently Asked Questions

Can Sirona Products be used with OSONE Chillers?

Yes! Sirona pairs great with OSONE® Chillers helping maintain fresh and clean water for months. Couples seamlessly with the bacteria-eliminating capability of UV light in the Pro Chiller.

How to use Sirona in my Cold Plunge?

Sirona is best used after clean water fill-up. Once your cold plunge is filled with clean water, turn on the chiller to ensure continuous water flow and then simply add 20ml of Sanitizer, 60ml of Oxidizer and Calcium Booster (if needed) directly to the water in your plunge. These measurements are based on water level to the top return hole of your HydroTub or HydroBarrel.

The continuous water flow will cycle the solution throughout your cold plunge. Repeat as needed based on usage and water quality.

Should my water look cloudy after application?

Yes, we recommend 24 hours to let all of the solution cycle throughout the plunge before the water becomes crystal clear.

How often should I use Sirona?

We suggest syringing the proper doses into your cold plunge water every 2 weeks, max 4 weeks.

When should I not use Sirona?

For Sirona to work properly, water flow is essential. If you're not using a chiller that provides continuous water flow, and instead are cooling your water with ice or relying on natural temperatures, we do not recommend Sirona, as it will not function as intended without water flow.
