If you’ve ever lifted the cover of your spa and noticed frothy, foamy water, you’re not alone. Many Portland spa owners deal with this problem, especially in the fall when spas get more use during chilly evenings. The good news? While spa foam is frustrating, it’s usually easy to fix once you understand the cause.
Common Causes of Spa Water Foam
Foam in your spa doesn’t appear by accident. It’s often a sign that your water chemistry or maintenance routine needs a little attention.
- Body Oils and Lotions: Everyday products like sunscreen, deodorant, and moisturizers break down in the water, creating a soapy effect.
- Detergent Residue: Bathing suits washed with laundry detergent may carry leftover soap that transfers into spa water.
- High Organic Load: Sweat, hair products, and even dead skin cells can overwhelm your spa’s sanitizer if the water isn’t treated properly.
- Low Calcium Levels: Water that’s too soft can destabilize and allow foam to form more easily.
Identifying the root cause is the first step toward clear, inviting spa water.
Myths About Foamy Spa Water
Before tackling the problem, it’s helpful to clear up a few misconceptions:
- Myth 1: Foam means your spa is unsafe.
Not true — foam is more of an annoyance than an immediate health risk. However, it does indicate water balance issues that should be addressed.
- Myth 2: Draining and refilling is the only fix.
While sometimes necessary, foam can often be corrected with targeted treatment and maintenance.
- Myth 3: Foam is just “normal.”
Spa foam isn’t a sign of proper operation — it’s a clue your spa needs more attention.
Quick Fixes for Spa Foam
If you notice foamy water, try these steps before scheduling a professional visit:
1. Shock the Water
A chlorine or non-chlorine shock treatment oxidizes organic material, reducing foam and restoring water clarity.
2. Check Water Balance
Low calcium hardness is a common culprit. Test your spa water and adjust levels as needed.
3. Rinse Off Before Soaking
Encourage everyone to take a quick shower before using the spa. This small habit dramatically reduces oils, lotions, and contaminants.
4. Wash Bathing Suits Without Detergent
Rinse suits in plain water instead of laundry soap to prevent residues from seeping into your spa.
5. Clean or Replace the Filter
Foam can build up when your filter isn’t trapping particles effectively. Regular cleaning or replacement keeps water clean and clear.
