How do you increase MPS in a hot tub?

Author: Lura Hoppe MD  |  Last update: Friday, March 25, 2022

Shocking the water with chlorine will eliminate excessive chloramines, but it requires raising the spa chlorine level to approximately 10 ppm. After super-chlorinating the water, bathers must wait until the chlorine residual comes down to the acceptable range, between 1 ppm and 5 ppm, before getting back in the water.

What does MPS do in a hot tub?

MPS Shock (MonoPeroxySulfate) is a non-chlorine compound that will do the job of oxidizing allowing the sanitizer to do the more important job of destroying the microorganisms. Regardless of which sanitizer you use, shocking is essential for clear, clean hot tub water.

How long does MPS last in a hot tub?

The spa owner is required to manually add MPS to the spa with each use, and a small amount of chlorine once a week. The silver ion cartridge should be replaced every three months, and the ozone unit will need to be replaced every 4-5 years.

Can you add too much oxidizing shock?

If too much is added, it can cause the overall pH level of the pool to drop for a sustained period, which you'll then have to raise. Whereas, with a chlorinated shock, if you overdose the pool on it, all you have to do is wait a few extra hours for the sun to burn off the chlorine.

How to Raise Hot Tub Alkalinity

Should I shock my hot tub after every use?

Dead skin and other elements like hair may end up dropping in the hot tub, leaving the tub in a mess. It is essential to shock the hot tub frequently – at least once every week. It is important to use Chlorine shocks as well as non-Chlorine shocks.

How much shock should I put in my hot tub?

Measure 17g of non-chlorine shock per 1500 litres or 35g of chlorine shock per 1500 litres (consult the label instructions as this can vary based on chemical quality and brand). Carefully add the required shock to the hot tub. Leave the cover off for approximately 20 minutes.

What does potassium Monopersulfate do?

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.

How do you add Dichlor to a hot tub?

Sodium Dichloro-S-Triazinetrione (Dichlor) is a granular chlorine that can be added to your hot tub water in small, measured doses before and after each soak. One or two Tablespoons of Dichlor before each soak is usually enough to sanitize the water and quickly kill germs on your body as you slip into the water.

Does MPS raise or lower pH?

Monopersulfate does not cause odors or irritation. Caution: The standard “shock” dosage for monopersulfate is 2 lbs. per 10,000 gallons of water. Overdosing may cause a dramatic drop in pH and lower total alkalinity as the pH of monopersulfate is approximately 2.3 (acidic).

How do you test MPS in a hot tub?

If your MPS levels are low, that means you still have organics floating around in your spa, creating havoc and cloudy water! So, the moral to the story is, start off by adding about 1 tablespoon per person of oxidizer to your water after each use. Run the jets on a clean cycle, about ten minutes, and then test for MPS.

How often add chlorine to hot tub?

You should put chlorine in your hot tub at least once a week. However, some people prefer to add a small amount after each use. Finding the best water care routine will depend on how often and how many people use it. Chlorine levels should be between 1.5 and 3.0 ppm.

Can you add more jets to a hot tub?

No, not all hot tubs have jets. Some hot tubs may allow you to add more jets, but it should be done by a professional as it is a very mechanical process that may require more pumps as well. What is this? Even inflatable hot tubs can have jets, although they are usually air jets and not water jets.

How many jets should a good hot tub have?

A seat with 30 jets looks nice, but a seat with 3 jets across your shoulder blades and 2 jets sweeping and massaging up and down your back will be far more effective than the 25 stationary jets.

What is the difference between potassium monopersulfate and potassium peroxymonosulfate?

There is no difference, just different names for the same thing. The full name is potassium peroxymonosulfate.

Can you add too much shock to hot tub?

The bottom line is that over-shocking is possible, but being responsible with your chemicals and timing will help you to avoid it as often as possible!

How do you test for Monopersulfate?

Monopersulfate is an oxidizing agent used in mineral purification systems such as Frog, SpaFrog, Nature2, PoolRx, or SpaRx. To test, just dip your AquaChek Monopersulfate strip into your pool or water for a quick second, and remove it immediately. You'll get results in just seconds.

Can you add shock and chlorine at the same time to a hot tub?

Can I add shock and chlorine at the same time? No, you should not add shock and chlorine at the same time. The best thing to do is add spa shock treatment first and allow that to work, then test and add chlorine if needed.

How long after chlorine can I add shock?

You should wait one hour per pound of shock product added, and then test the water to confirm the pH and chlorine are in the proper range before letting anyone enter the pool. As a reminder, you want your pH to be between 7.2 and 7.8ppm and your free available chlorine to be 1-4ppm for safe swimming.

Is spa shock the same as chlorine?

Spa Shock is commonly available in two different forms. There is chlorine based shock (Sodium Dichlor), which increases your sanitizer levels as well as shocking the water, and non-chlorine shock (potassium monopersulfate or MPS) which is purely for oxidizing the water.

How often do you put bromine in hot tub?

You should ensure that your hot tub bromine level is always between 3-5ppm (parts per million. The addition of bromine will depend upon usage and bathing habits. It could be daily or every 2-3 days (for 3ppm add 12g per 1500 litres).

Why is the water in my hot tub Green?

Green hot tub water can be caused by algae which is usually a sign of insufficient sanitisation level (Chlorine or Bromine) in your tub. Minerals such as iron, copper, and manganese can also make the water turn.
