Can you hop in anyway? Hot tub foam is a common problem that occurs when water, air and surfactants — a scientific term referring to the compounds that lower surface tension between a liquid and a gas — collide. When the three meet, the surfactants form a barrier between the water and the air, resulting in foam. Foam can occur in a few different forms. It can have a soapy look that covers the top of the water or it can be cloudy, making the surface of the water a murky white.
The primary culprit of foam is failing to sanitize your hot tub water weekly or after heavy use, such as a hot tub party. Lotions, cleansers, makeup and even laundry detergent leave our bodies and swimsuits when we soak in water.
Foam will appear if the pH balance of your hot tub water is off. This is caused by using cheap chemicals or inaccurately mixing them. Water with low calcium or too much pH or alkaline can lead to cloudy water. If you use your hot tub frequently, you yourself could be causing foam to appear.
When you soak in your hot tub, you shed dead skin cells as well as oil from your skin. If you snack or drink when you are in the hot tub, crumbs and spills will play havoc with your water balance. Keep beverages and food away from your spa to avoid unnecessary contamination. The simple answer is: hot tub chemicals. We use the Langlier Index to ensure oure water quality. However, that pure white foam is still forming on the water when the jets are started.
Any rhoughts? Hi there, We usually have foamy hot tub water in our hot tub. It has been manufactured in and we changed it every 2 months.
If you have an answer to this problem, please tell me! Hi Shan, The foam could be caused from low calcium hardness, or the pH and alkalinity being out of balance. Those products do a great job keeping the foam away. You run that through the system right before draining, and if there is anything in your piping that is helping cause the foam, that will get rid of it.
I hope this helps, and please let me know if you have any other questions. Thanks, Mark SpaDepot. When my spa is cloudy and I add a clarifier and turn my jets on high, I get a green slime in the foam. Any suggestions?
You could have some hidden bacteria or other microoganisms in the plumbing and jets that would be dislodged with the Flushing. Also, be sure to monitor and balance your spa water since low levels of pH and sanitizer can cause shades of green water. If it is, then you know you should replace the filters. As a general rule of thumb, we recommend rinsing out filters the weekly with a garden hose, deep cleaning them with filter cleaner at each water change, and replacing them annually.
If you have not changed your water since the summer, I would recommend the following course of action:. Use a bottle of Spa System Flush in the tub 2. Drain the water 3. Clean the shell of the tub with Clean All 4. Clean or replace the filter depending on the age and condition of the filter 5.
Refill the tub, paying special attention to calcium hardness. We stayed here last year and the hot tub foamed up to the point it kind of ruined the experience.
We would like to know if there is something we could do to minimize or prevent the foam for our long weekend without spending a lot of money maintaining a hot tub that should already be maintained. I just want to be able to make our time stress free.
Considering some Scum Buster and maybe some sodium dichlor. Any advice would be greatly appreciated. I would strongly recommend getting in touch with the property manager and asking if they can do a drain and refill on the tub before your stay.
First, shock the water with Dichlor and rinse out the filter. Then, after each use, shock with Oxy Spa non chlorine shock per the instructions on the bottle. That will go a long way towards keeping the water safe and foam free. Hi James, There could be lots of reasons, but the most common is not shocking the water frequently enough. I have a hot tub that usually stays clean and foam free. We occasionally have a guest that will get in and without fail, after a few minutes, the water will get foamy with a grey looking scum.
After his departure, I always have a ring so the tub must be emptied, cleaned and the filter cleaned or changed. Is this coincidence or something about his body? It is just a little gross!! Am i losing my mind.
Try using Easy pH instead. It will raise only the pH, and leave TA alone. Give us a call at and we can make sure you get everything you need for a foam free experience. My hot tub is clear as can be whenever we open it up. The only time it foams up is when the jets are running and then as soon as we turn the jets off it clears up.
Why is this? The fact that the foam only presents itself when the jets are on is due to aeration. My hot tub has been turn off due to electrical problems for about 2 mos.
When I opened the cover the water was crystal clear and cold. I added chlorine to it and the water developed foam. What do I do now? Hi David, Since the water has been sitting for 2 months without circulation, I recommend doing a drain and refill. I just purchased an inflatable hot tub. The first few days went great. Today, i turned on the jets and it looked like my washing machine overflowed with soap. It finally calmed down, but it was crazy. My pH levels are fine, no makeup, or anything out of the ordinary.
I circulate it about x a day. So often, this foaming is due to inorganic matter in the water. Shocking breaks down those compounds, reducing or eliminating foaming. Water is sparkling. Consistently adjusting the ph and alk as they daily fluctuate. Have new tub for 10 months now, on 4th filter, have changed water 5 times now.
Its fantastic for 4 weeks, then the foam starts. Use foam away and it stops, but it leaves scum type deposits, and you can see the chemical floating on top. We fight this battle for 3 weeks or so, then we flush the jets and drain the tub. Please check our Lead Times page in the Info Section before ordering any furniture. Here are the common causes of hot tub foam: Hair care products such as shampoo, gel, mousse, hair spray, etc.
Body lotions and deodorant Makeup Laundry detergent or soap Cheap hot tub chemicals, too many chemicals, or total dissolved solids TDS Drinks The only thing that should go in your hot tub water are people and and trusted, high quality hot tub chemicals.
Wash off all the soap residue, makeup and other body chemicals. Make sure bathing suits are cleaned and rinsed with fresh water before getting in the hot tub. Long-haired soakers should wear a baseball cap to keep their hair up. Get the right chemicals from a trusted source like Ultra Modern.
Drain and clean a hot tub regularly.
