Hot Tub Things® Spa Defoamer – Instant Anti-Foam Treatment for Hot Tubs & Spas

What Causes Foam in Hot Tubs?

Foam occurs when the surface tension of water is altered by contaminants. Common culprits include:

• Body Products: Oils, lotions, deodorants, and cosmetics create a film that traps air bubbles
• Detergent Residue: Laundry soap left in swimsuits acts like dish soap in your spa
• Low Calcium Hardness: Soft water (below 150 ppm) foams more easily
• High TDS: Total dissolved solids accumulate over time, affecting water quality
• Poor Filtration: Dirty filters can't remove foam-causing contaminants
• Organic Matter: Leaves, pollen, and other debris break down and create foam

Prevention Strategies:

While Hot Tub Things® Spa Defoamer provides instant relief, preventing foam saves time and extends water life:

1. Maintain Proper Calcium Hardness: Keep levels between 150-250 ppm
2. Shower Before Soaking: Remove oils, lotions, and cosmetics
3. Rinse Swimsuits: Use only water – no detergent – when washing spa swimwear
4. Clean Filters Regularly: Replace or clean every 2-4 weeks depending on usage
5. Shock Weekly: Oxidize organic contaminants before they cause problems
6. Drain & Refill: Replace water every 3-4 months (or per manufacturer guidelines)
7. Test Water Weekly: Maintain balanced chemistry to prevent multiple issues
