You're probably wondering what you're doing wrong if you're getting foaming water in your hot tub. This isn't the case; hot tub foam can show up anytime, even if you're doing everything right. 

We've put together a guide on how to get rid of foam in your hot tub, so you can relax and enjoy your hot tub without worrying about this pesky problem.

What Causes Foam in Hot Tubs?

Most hot tub owners have experienced the frustration of foamy hot tub water. While it may look harmless, foam can result from several issues and cause problems with the hot tub's filtration system. To keep your hot tub water clean and clear, it's essential to understand what causes behind this foam. These are:

  • Soap and laundry detergent
  • Oils and lotions
  • Biofilm build-up
  • Poor water balance

Soaps and detergents

One common cause of foamy hot tub water is the presence of soaps and detergents. When people enter a hot tub, they often bring soap or laundry detergent traces on their bathing suits. These substances can create foam when they mix with the hot tub's water. Similarly, if used in the hot tub, bubble bath products can cause foaming. To prevent hot tub foam of this kind, ask everyone who uses the hot tub to rinse off thoroughly before hot tub use.

Oils and lotions

Another common cause of hot tub foam is oils and lotions. When people enter a hot tub, their skin usually comes into contact with the water. This can cause body oils and lotions to transfer into the hot tub, creating foamy water. Even things like sunscreen or makeup can wreak havoc on hot tub water, so it's best to avoid using them before getting in. To prevent this type of foam, it's essential to ensure everyone who uses the hot tub has washed off thoroughly before getting in.

Biofilm build-up

Biofilm build-up is another common cause of foamy hot tub water. Biofilms are thin layers of bacteria that can form on surfaces exposed to water. Hot tubs provide an ideal environment for biofilms to grow and can quickly build up on the surface of the hot tub's water. As biofilms grow, they release substances that can create foam. To prevent biofilm build-up, it's essential to clean your hot tub and maintain proper water chemistry regularly.

Poor water balance.

Poor water balance can also cause foam water. If the pH, alkalinity, or calcium levels in the hot tub's water are too high or too low, it can produce foamy water. To prevent this type of foam, you must regularly test your hot tub's water and adjust the levels as needed. By understanding what causes foamy water in hot tubs, you can take steps to prevent it from happening in your hot tub.

You see, many factors are affecting you there; by diagnosing and treating the source of your foam problem, you can hopefully resolve it and enjoy your hot tub without any more unwelcome surprises.
