What is monopersulfate in a hot tub?
Monopersulfate is a non-chlorine shock treatment that has become very popular with hot tub and spa owners and requires only a short waiting period before soakers and bathers can re-enter the water. It also cuts down on the odors and irritation caused by elevated levels of chlorine.
Does potassium Peroxymonosulfate lower pH?
Furthermore, it lowers the pH and the total alkalinity. KMPS shows up as combined chlorine in the DPD test and as free chlorine in the FAS-DPD test.
Does potassium Peroxymonosulfate kill algae?
1. The effective constituent of potassium peroxymonosulfate in disinfection and oxidation is active oxygen, which is produced when it contacts with water. Up to 63% of the algae is killed when the dosage is 0.6mmol/L under 20.5 o C for 20min.
What is sodium monopersulfate?
Monopersulfate is a non-chlorine shock alternative that has gained some popularity over the years. It comes in granular (powder) form and can be added directly to the water. Although monopersulfate is effective at burning off chloramines in a chlorine system, it is a weak oxidizer especially compared to chlorine shock.
When should you shock your hot tub?
Generally it is recommended that you shock your hot tub once a week – more often if it’s seeing heavy use. If your levels are all good, but the water is a bit cloudy or doesn’t quite smell right, it’s time for a shock. You should also shock the tub if you haven’t used it for an extended period of time.
Why do you shock a hot tub?
The main reason anyone shocks their hot tub is to clean the water, but it also helps to clear cloudy water. Other reasons to shock your hot tub include: To kill bacteria – Chlorine based shock treatments are designed to sanitise the hot tub water and ensure it is safe for bathers.
Is potassium Monopersulfate toxic?
Acute Toxicity: This product is corrosive to all tissues contacted and upon inhalation, may cause irritation to mucous membranes and respiratory tract.
Is potassium Monopersulfate the same as potassium peroxymonosulfate?
There is no difference, just different names for the same thing. The full name is potassium peroxymonosulfate.
What is potassium peroxymonosulfate used for?
Potassium peroxymonosulfate (also known as MPS, KMPS, potassium monopersulfate, potassium caroate, the trade names Caroat and Oxone, and as non-chlorine shock in the pool and spa industry) is widely used as an oxidizing agent. It is the potassium salt of peroxymonosulfuric acid.
Is potassium monopersulfate toxic?
What is Peroxymonosulfate used for?
What is the purpose of monopersulfate in water treatment?
The role of monopersulfate is to provide effective non-chlorine oxidation — in other words, to react with organic contaminants and maintain or restore water clarity. Non-chlorine oxidizers, like similar chlorine products, are intended to be used for supplemental treatment.
What’s the difference between MPs and sodium monopersulfate?
MPS will reactivate bromide to bromine fairly quickly. Sodium Monopersulfate should be essentially identical, just with a sodium instead of potassium in a way that shouldn’t make any difference in a pool/tub. That suggests that whatever you were using that was labeled Potassium Peroxymonosulfate was not really Potassium Peroxymonosulfate.
What’s the difference between persulfate and monopersulfate?
Persulfate by itself does not react with bromide (nor chloride, but it does react with iodide). With monopersulfate, it takes longer to oxidize bromide to bromine. Ozone reacts faster and chlorine even faster (to oxidize bromide to bromine). I’m pretty sure I got the names right, but I’ll check next time I service that particular tub.
What kind of oxidizer is potassium monopersulfate?
Potassium Monopersulfate (monopersulfate, KMPS or MPS) is a white, granular, free-flowing peroxygen that provides powerful non-chlorine oxidation for a wide variety of uses. It is the active ingredient in most nonchlorine oxidizers used for pool and spa/hot tub oxidation.

What is the reaction byproduct of monopersulfate?
The reaction byproducts are harmless sulfate salts. The key concept to note here is that monopersulfate products will NOT remove existing combined chlorine but only prevents the formation of new combined chlorine.
