Perfect conditioner for my portable hot tub

I use one entire container in my saluspa portable hot tub every 3 months.  When this is used in addtional to daily chlorine checks it keeps my hot tub clean and clear.  Better for skin too.

Great product

Keeps the PH in my spa almost perfect for three months..


Spa Marvel is an amazing water conditioner for your hot tub or spa. You can feel the difference! The water feels soft and silky on your skin. It is easier to maintain balanced water with less added chemicals when you condition your water with Spa Marvel. I have been using this product for over a year and will never switch to a different brand for my hot tub!

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.
