My neighbor’s hot tub used to smell like a bleach bottle. One scoop of potassium peroxymonosulfate spa shock and the water turned silky in twenty minutes. No chlorine fog, no stink—just clean bubbles and happy guests. That tiny white grain is the cheat code every spa kid now shares by text.

A two-pound pouch runs twelve bucks shipped. Break it down: one teaspoon per 500 gallons means each spa session costs less than the foam on your coffee. The potassium peroxymonosulfate price stays flat year-round, unlike chlorine tabs that spike every summer.
Flip the bag and you’ll spot potassium peroxymonosulfate sulfate triple salt. That’s the white free-flowing granule that dissolves without grit. It’s stable until 80 °C, so it won’t gas off in a hot trunk like cheap shocks.
Potassium peroxymonosulfate uses stretch far. Campers stir a pinch into river water; five minutes later it’s drink-safe. Dentists dunk tools in a KMPS soak instead of bleach. Farmers shock livestock troughs without harming gills. Same bag, three jobs.
Each crystal carries KHSO5, the active oxygen punch. It rips apart slime, lotion, and dead skin without adding chlorine smell. Spot KHSO5 on the label and you know you’re holding real deal shock, not filler salt.
Don’t let cloudy water kill the vibe. Tap the orange “Buy KMPS” button, grab the 5-pound bucket, and we’ll toss in a free scoop that measures perfect teaspoons. Hot tubs wait for no one—order tonight, soak tomorrow.
Fifty-pound drums drop to $2.20 per pound—half the shelf price.
Yes, potassium peroxymonosulfate spa shock works in pools; just scale up the dose.
Absolutely—KHSO5 plays nice with salt cells and won’t throw off salinity.
Fifteen minutes is the norm; just wait until the white grains vanish.
