While foam is quite common in hot tubs that are used a great deal, having an excess amount of it is something that should be dealt with. Foam is created by dissolved solids in your hot tub water. These solids will include laundry detergent, deodorant, lotions, makeup, etc. Utilizing too much water care products will also cause your water to foam up.
While there are several ways to prevent solids from arriving in your hot tub, the easiest way is to simply shower before entering the water. Showering will flush all of the chemicals and waste off your skin and block it from getting into your hot tub water.
Once your hot tub starts foaming, here are some steps to take to clear up the water:
- Test your water. This is an important guiding step to take. Make sure all of your sanitizers, alkalinity and pH are balanced. Also, double-check your TDS levels. If one of these levels are unbalanced or your TDS levels are extremely high, it could be time for you to drain and re-fill your tub.
- Scoop out the foam. Most occurrences of excess foaming can be resolved by simply removing the foam and assuring that your chemical levels are correct.
- Replace or thoroughly clean your filter. This will prevent the water from creating more foam.
- Shock your tub with your sanitizer system. We suggest doing it with Chlorine, however people have seen success from doing it with non-chlorine sanitizers. While shocking, run your jets on high and have your cover half open to vent out the gases.
- Using “Foam Free” will help suppress some of the foam.
We typically recommend Hot Tubs are drained and filled approximately every 3-4 months and this may be a sign you are nearing this interval. You can also help prevent hot tub foam by routinely using an oxidizer after each use and utilizing a floating oil absorber, such as a “Hydro Mop” and adding an enzyme product such as “Purezyme” which naturally breaks down the biofilms which contribute to foam.
If you have fresh water and are experience foaming, it could be a result of low calcium hardness. Low calcium levels (which can also damage equipment) will decrease surface tension in the water and allow for excessive suds. To prevent this issue, take a water sample to your local Beachcomber Hot Tubs dealer to analyze and balance water including calcium hardness level. If low, use “Protect” calcium increaser.
Beachcomber Hot Tip: Asking people to restrain from dunking their heads under water is a great way to slow down the increase of dissolved solids. Also, having a Beachcomber Heatshield will help keep natural dissolved solids out of the water, as well as keep your heating costs down.
