SpaPure Oxidizing Shock | Non-Chlorine Spa Shock

• 1 x SpaPure Oxidizing Shock (2.2 lb resealable container, granular)

• Chlorine-free oxidation — powered by potassium monopersulfate, so it cleans without adding chlorine
• Restores water clarity — clears the haze and dullness left behind by bather waste
• Eliminates non-microbial contaminants — oils, sweat, lotions, and other organics that sanitizer alone struggles to keep up with
• Won't disturb your water balance — adds no chlorine, calcium hardness, or cyanuric acid
• Surface-safe — used on all spa surfaces with no risk of fading or bleaching shells, pillows, or covers
• Fast turnaround — the spa can be used again about 15 minutes after application

The active ingredient, potassium monopersulfate, releases active oxygen into the water. That oxygen chemically breaks down the organic compounds bathers leave behind — the oils and waste that cloud water and consume sanitizer — and converts them into harmless byproducts that filter out or gas off. The result is clearer water and a sanitizer that isn't fighting an uphill battle.

Unlike a chlorine-based (dichlor) shock, an oxygen shock does its work and leaves nothing extra behind. There's no chlorine spike to wait out and, importantly, no cyanuric acid added to the water.

Pro Tip: That "no cyanuric acid" point matters more than it sounds. Chlorine-based shocks slowly build cyanuric acid (CYA) in the water, and too much CYA locks up your chlorine and makes it sluggish. Because SpaPure Oxidizing Shock adds none, it's especially smart for spas you don't drain and refill often — you can shock as often as you need without that slow creep.

Apply weekly, after heavy use, or any time the water looks slightly hazy or dull. Shock more often if the spa sees frequent or heavy use. Always broadcast the product uniformly over the surface of the water with the pump running and the spa filtering.

1. Turn on the circulation system.
2. Add 1.5 ounces (about 2 tablespoons) for every 200 gallons of water, broadcasting it evenly over the surface.
3. Continue circulating for 15 minutes. The spa may be used 15 minutes after application.

Pro Tip: Leave the cover open for the 15 minutes the spa is circulating after you shock. That lets the oxidized contaminants gas off into the air instead of getting trapped under the cover — and it's the simplest way to knock out that faint "used water" odor that tells you a shock was overdue.

SpaPure Oxidizing Shock is the oxidizing/shock step in your routine and slots in alongside virtually any sanitizing system. It pairs with chlorine and bromine programs, and it complements mineral and salt-based systems as the weekly oxidizer that keeps organic waste from building up.

It's safe on all spa surfaces — acrylic shells, headrests, pillows, and covers — so there's no need to worry about fading or bleaching the way you might with harsher products. For a complete weekly routine, use it together with SpaPure test strips to confirm your sanitizer and balance before and after shocking.
