If you’ve lifted the lid on your hot tub and found a layer of foam floating on top, you’re not alone. Foam in spas is a common issue throughout the South Okanagan, especially in the warmer months. But what causes it, and how do you fix it?
What Causes Foam in Hot Tubs?
Foam usually means your water is unbalanced. Common causes include:
Body oils, lotions, and cosmetics are affecting the chemical balance
Buildup of dissolved solids
Laundry detergent left in swimwear
Low calcium hardness or alkalinity
Left unchecked, foamy water can affect the health of your spa and your enjoyment.
Is Foam Dangerous?
While foam itself is not necessarily harmful, it’s a sign that your water may not be properly balanced. Unbalanced water can irritate your skin and eyes, reduce the effectiveness of sanitizers, and even lead to equipment wear over time. The sooner you address it, the better your spa will perform – and the longer it will last.
