Why Skin and Eye Irritation Happens

Skin and eye irritation can show up in a few ways. Your eyes might sting, even if you didn’t get water in them. Your skin might feel itchy or dry. Some people may even get a small rash.

There are many reasons this can happen. Most of the time, the water in your hot tub is out of balance. Sometimes the sanitizer is too low. Other times, the sanitizer is “tired” and not working well anymore. And in some cases, a person may be sensitive to a certain product or brand.

You’ll also see the term ppm, which means “parts per million.” It’s how we measure things like sanitizer in your hot tub.

1. Causes of Skin and Eye Irritation

Out‑of‑Balance Water (Especially pH)

Your skin likes water that is not too low or too high in pH.

• Below 7.0 can make skin itchy and dry, and eyes sting.
• Above 8.0 can cause dry skin, rashes, and irritated eyes.

When pH is off, your water feels harsh instead of soft.

Low Sanitizer

Sanitizer keeps bacteria out of your hot tub.
If your sanitizer stays low — especially around 0 ppm — germs can grow. This can make your skin and eyes feel irritated.

Tired Sanitizer (Too Many Contaminants)

If your hot tub smells “chemical‑like,” it often means the sanitizer is tired. It has used up its strength fighting off oils, lotions, and other stuff in the water. This can cause the same problems as low sanitizer.

Allergies or Sensitivities

This one is tricky.
Some people react to high sanitizer levels. Others react to a certain brand, even if the product type is the same. Every situation is different, but we can help you figure it out.

2. How to Fix Irritating Conditions

Step 1: Take a Break From the Hot Tub

Don’t go back in until your skin and eyes feel and look normal again.

Step 2: Test Your Water

Bring a sample to us, or test it at home.

Check these levels:

• pH: 7.2 to 7.8
  • To lower pH: pH Minus or Lo ’n Slo
  • To raise pH: pH Plus or Balance Pak 200
• Sanitizer (bromine or chlorine): 3.0 to 5.0 ppm
  • Add granules if needed
  • Check your puck dispenser for blockages or empty spots

Step 3: Shock the Hot Tub

Use an oxidizer to clean up tired sanitizer.
Good options include:

• Clean ’n Clear
• Spa Lite

Step 4: If It Still Doesn’t Feel Right, Call Us

If the irritation keeps happening, it may be an allergy or sensitivity. We can help you figure out what’s causing it and what products will work better for you.

3. How to Prevent Irritation in the Future

Rinse Off After Your Soak

This helps if you have sensitive skin and removes leftover sanitizer.
