Foam in hot tubs is no fun for any hot tub owner. Foam on the surface of the water is not only ugly but also a sign of poor water quality. Knowing the causes of foamy hot tub water and how to prevent and get rid of it will help you have a clean hot tub experience.
Hot Tub Foam
Foamy hot tub water is a common problem many hot tub owners face. This foamy water can be caused by many things including improper water chemistry, foreign substances introduced into the water and poor maintenance practices. Knowing what causes hot tub foam is key to preventing and getting rid of it.
One of the main causes of foamy hot tub water is contaminants like body oils, lotions and soap residue. These substances reduce the surface tension of the water and cause foam to form. Using cheap chemicals or not maintaining the correct water balance can make it worse. Testing and adjusting the pH and sanitizer levels regularly can help keep the water balanced and prevent foam.
Another cause of hot tub foam is the buildup of organic matter and debris in the water. This can happen if the hot tub filter is not cleaned often or the water is not changed often enough. Knowing these causes and taking action can keep your hot tub water clean and foam free.
What causes foam in a hot tub?
How do lotions and detergents cause foam in hot tub water?
Lotions and detergents are the common culprits of foam in your hot tub. When you use the hot tub, residues from body lotions, shampoos and detergents on your bathing suits get mixed with the hot tub water. These substances reduce the surface tension of the water and cause foam. The more products you use on your skin and bathing suits the more likely you are to have foamy water in your hot tub.
Can bathing suits cause foamy hot tub water?
Yes bathing suits can cause foamy hot tub water. Bathing suits carry soap residue from washing which can cause foam when they come into contact with hot tub water. Even if you rinse your bathing suits thoroughly small amounts of detergent can still be present and cause foam. Make sure bathing suits are as soap and detergent free as possible before getting in the hot tub.
What’s the role of surface tension in hot tub foam?
Surface tension is the key to hot tub foam. Surface tension is the elastic tendency of a fluid surface to be as small as possible. Substances like lotions, detergents and body oils are introduced into the water and disrupt the surface tension and cause bubbles to form. These bubbles accumulate on the surface of the water and cause the foamy appearance hot tub owners see.

What can hot tub owners do?
Hot tub owners can do several things to keep their hot tub clean and foam free. First shower before using the hot tub to remove body oils, lotions and other contaminants. Second, don’t use soaps and detergents on bathing suits and rinse them thoroughly before getting in the hot tub. Third clean the hot tub filter regularly to make sure it’s free of debris that can cause foam. And fourth maintain the correct water balance by testing and adjusting the pH and sanitizer levels.
How does pH level help prevent foam?
Maintaining the pH level of your hot tub water is key to preventing foam. The pH level measures the acidity or alkalinity of the water and an imbalanced pH can cause many water quality issues including foam. When the pH is too high or too low it can reduce the effectiveness of sanitizers and cause the water to become cloudy and foamy. Testing and adjusting the pH regularly will keep the water balanced and prevent foam.
Why rinse before getting in the hot tub?
Rinsing before getting in the hot tub is important to prevent foam. When you rinse off in the shower you remove body oils, lotions and other contaminants that can cause foam in the hot tub water. This simple step will reduce the amount of foam on the surface of the water. And rinsing will also keep the hot tub water clean and extend the life of the hot tub filter by reducing the amount of debris it has to filter out.

What’s the importance of calcium hardness in hot tub water?
Calcium hardness is key to hot tub water quality. Calcium hardness is the amount of dissolved calcium in the water. If it’s too low the water becomes corrosive and can damage the hot tub components.
