Eliminating the Foam in Your Hot Tub or Spa

One of the most common difficulties expressed by hot tub and spa owners is the large amount of foam residing at the top of the water. This is a very common problem associated with hot tubs and spas, fortunately it can be easily fixed. In order to fully understand the solution to your problem, you need to first recognize the cause for the foam in the first place.

Hot tub foam can be the result of many factors. The most common cause of foam is the particles that are released from bathers when they first enter the spa. Dead skin cells, bacteria, residue from swimsuits and particles from tanning or body lotions are the most common reasons for the foam at the top of the water. These particles, combined with the particles released during chemical applications, can result in a high amount of total dissolved solids in the water. The higher the total dissolved solids in the water, the more foam you will acquire in your hot tub.

Now that we've established the reason for the foam, we must consider the most effective solution to the problem. Defoamers are products that are used in hot tubs and spas to decrease the amount of foam in the water. There are a number of different types of defoamers on the market which are effective in eliminating the foam; however, it is important to recognize that even though the foam is gone, the unhealthy particles remain in the water. Defoamers simply make the foam disappear, but most products do not completely eliminate the particles which created the foam in the first place.

If you are concerned with the way your hot tub looks with the foam, a defoamer will be an effective solution to your problem. However, if you are concerned with the health issues related to the foam, a defoamer is not an effective solution. The best way to ensure both the foam and the health concerns are eliminated is to completely empty the existing water in your hot tub and replace it with new, fresh water. This should be done approximately every three months in order to ensure healthy water, even if there is no foam in your hot tub.

If you are interested in purchasing a defoamer for your hot tub or spa, you have many options. Defoamers cost anywhere from $10 to $30, depending on the brand name you choose.
