The Best Hot Tub Chemicals for Utah’s Climate

Utah’s weather is tough on hot tubs. Dry air, cold nights, and mineral-heavy water can throw things out of balance fast. If you live in Park City or nearby, using the right chemicals can make all the difference.

Here’s what we recommend for keeping your spa clean and running smooth year-round.

1. Balance Your pH and Alkalinity

Utah water tends to be hard, which means pH levels can bounce around. That causes cloudy water, corrosion, and even damage to your equipment.

What to use:

• pH increaser or decreaser

• Alkalinity increaser

We recommend testing your water a couple of times a week, especially in the winter. If you’d rather not deal with that yourself, our spa maintenance plans take care of it for you.

2. Use a Non-Chlorine Shock

Guests, renters, and even just a weekend of heavy use can leave behind oils, sweat, and bacteria. A non-chlorine shock helps clean the water without making it harsh on skin or eyes.

What to use:

• MPS shock (potassium monopersulfate)

It works well in cold water and keeps your water looking clear between deep cleans.

3. Choose the Right Sanitizer

Chlorine and bromine both work, but the right one depends on how often your spa is used.

What to use:

• Bromine if your spa sits for long periods

• Chlorine if you use it regularly and want quicker adjustments

We use both for clients depending on their situation. If you’re unsure, we’ll help you decide what’s best during a service visit.

4. Control Scale and Staining

Minerals in Utah’s water can build up fast and leave behind white crust or cloudy spots. Over time, that can damage your jets and plumbing.

What to use:

• Scale control once a week

• Stain remover if your spa already has buildup

This is especially important if you’re on well water or your spa gets a lot of use.

5. Add Clarifiers and Enzymes

If your water still looks cloudy or has a funky smell, clarifiers and enzymes help clean up the stuff your filter can’t catch.

What to use:

• Clarifier drops after a drain and refill

• Enzyme treatments for rentals or heavy usage

Enzymes are great if you rent your property out often and want to keep the spa clean between guest stays.
