Fast and Frugal

I have ysed them for years. They do what they say…timely. This particular product is a must for easy and pleasant spa-ing

Spa Conditioner

My husband has always had a horrible rash from spa chemicals. He could not sit in his spa daily without having this horrible rash. I didn't know that we had options to help with this. First time using Marvel spa conditioner and literally within one week (sitting daily) he has no rash and skin is much softer. He does have psoriasis as well so we are watching to see what happens with his skin condition. So far so good.

Spa Marvel is a marvel!

This product is great. My husband says it says him lots of extra work

Great on my skin & hair!

After we started using Spa Marvel it changed our lives! We use our hot tub about 3 times a week and we have always delt with dry and itchy skin after we get out. We started using Spa Marvel and our skin and hair feel more moisturized after we get out of the hot tub then it did getting in! We swear on this product!!

So easy to use & skin feels amazing after!

It's crazy how easy this is to use! I only add this in our spa once every 3 months and my water stays so clear. Not to mention the way my skin feels afterwards.


Ask a Question
  • If i use Treatment and Conditioner do i still need to add bromine tablets to spa?

    Yes you still need to use chlorine or bromine. The Spa Marvel Treatment and Conditioner is an enzyme!

  • What happens if I go more than 3 months without adding another bottle of Spa Marvel?

    It is important to replenish Spa Marvel every three months, especially if you are trying to get as close as you can to having a hot tub without chemicals. You will need to use more sanitizer to maintain desired readings, pH and alkalinity may begin to wander, the soft-skin feeling will diminish and you may begin to encounter foaming and scum lines.

  • I only have a 250 gallons hot tub, do I only use ½ of the bottle of Spa Marvel every 3 months?

    You should add 1 full bottle of Spa Marvel for all tubs up to 500 gallons, regardless of size. Every time you get out of the spa, you take some Spa Marvel out with you. It is for this reason that you need to add more very three months.

  • How often should I change my water when using Spa Marvel?

    It is good practice to change your hot tub water every 3 months. Use Spa Marvel Cleanser prior to changing the water.

  • How long does Spa Marvel last? Will it ever expire?

    One full bottle of Spa Marvel will treat any tub up to 500 gallons (2000 liters) and will last 3 months with regular use. That is if you use it correctly! Spa Marvel has a 10 year shelf life.

  • How will I save using Spa Marvel?

    The cost of using Spa Marvel will be offset by savings realized through reduced chemical cost and reduced wear and tear on equipment, heaters, lids, and bathing suits.

  • Is Spa Marvel compatible with other spa water treatment products?

    Spa Marvel is compatible with all makes and models of spas so you do not need to worry about your spa. As for chemicals it is compatible with all water treatments including chlorine, bromine, salt water, biguanide products, ionization, ozone and ultra violet.

  • How do I know if Spa Marvel is working?

    You will be able to feel that Spa Marvel is working! After getting out of your spa your skin will feel moisterized. You will also notice you will use less sanitizer, it will help maintain your pH and Alkalinity and it will prevent foaming and scum lines!

  • Can I use Spa Marvel in place of my chemicals?

    You will still need to sanitize your spa by using a chemical line. Spa Marvel will naturally help you maintain and clean and clear spa and keep your levels where they need to be.

  • How long can I get into my spa after adding the conditioner?

    You can start enjoying your Spa Immediataly after you add the Spa Marvel Treatment & Conditioner.
