Get Rid Of Hot Tub Foam

How to Get Rid of HOT TUB FOAM | Swim University

Begin by determining whats causing your hot tub to foam. Test the levels of chemicals and sanitizer in your water and add more of each as needed to restore proper levels. Low levels of general hot tub chemicals are easily restoredjust add more and make sure they stay at the proper level. However, if the sanitizer levels have plummeted again within a day or two, youre probably dealing with a buildup of biofilm. Buy antibacterial hot tub cleaner and let it cycle through your piping system several times before replacing the water.

If your chemical and sanitizer levels seem to be fine, but your hot tub is still covered in a layer of oily bubbles and forming a ring around the edge, your water is contaminated. You have two options for getting rid of contaminant foam. For a faster solution, simply drain the water, scrub the hot tub shell, and refill your spa with clean water. If you dont mind waiting a few days, add an oil-absorbent sponge to the water and allow it to soak up the contaminants.

Pro Tip: Anti-foam chemicals for your spa are only a temporary solution and dont actually clean your water. Use sanitizer or special cleaning products to get rid of the underlying problem.

Is Foam In Spa Water Bad

If you have foam in your spa, it is simply a sign that the water is either overloaded with high TDS or is chemically out of balance. The foam in spa pools is not dangerous and is simply caused by the jets creating bubbles with the surfactants in the water. It is a common spa pool problem and means that your spa pool needs fresh water, or to be rebalanced in terms of pH, alkalinity, or calcium levels.

What Is Hot Tub Foam

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.

    What is the best Hot Tub Insulation Type?

    Of course you can drain your tub and get rid of some foam, but more importantly, you should be cautious not to allow it to build up again. Because there are so many potential causes, you must be aware and strategic in order to prevent future foam buildup.

    Heres what you can do to prevent foam:

  • Shower First. Make sure youre clean before you hop in your spa in order to wash off all the soap residue, makeup, and hair chemicals.
  • Wear Clean Bathing Suits. Residue from your bathing suits due to the type of laundry detergent can create a foamy substance, so make sure bathing suits are cleaned and rinsed with fresh water before getting in.
  • Use Quality Chemicals. If youre trying to save money, save money on anything else but chemicals. Dont buy the cheap kind as this can result in more problems than just a foamy hot tub.
  • Dont Spill Drinks. Drinking while soaking? Make sure you drink responsibly. By that, we mean dont spill whatever it is youre drinking.
  • Test Your Water Regularly. Use hardness test strips once a week to evaluate your tubs hardness level. If youve got an imbalanced pH level, consider a pH decreaser or shock.
  • Clean Your Water Regularly. As mentioned, a full hot tub drain and cleaning is recommended every three to four months.
  • Another tip we suggest is purchasing an anti-foam chemical, as this is the perfect option to use if youre short on time and arent able to clean out the water.

    How Much Foam Is Normal In A Hot Tub

    As a general rule, there should be zero foam in a hot tub. However, bubbles are naturally occurring in hot tubs with jets on, and there is a large difference between bubbles and foam.

    Hot tubs are not bubble baths, they should not have foam. While the foam is usually harmless to humans, it is an indicator of an underlying issue or issues with your hot tub.

    As previously stated, you will want to check the chemical balance of your hot tub. Use a chemical test kit to check the pH levels. Water with a pH level that is greater than 7.8 ppm has too much pH in it.

    Low calcium levels in your spa can decrease the surface tension of your spas water. This allows excessive foaming on the water to occur.

    Additionally, low calcium levels in your water can damage your hot tub.

    Using test strips is a really easy and effective way of figuring out your hot tubs chemical balance. To use a test strip, just dip it in the hot tub water.

    Then wait fifteen seconds. The test strip will turn into a color, and you should compare the color that appeared with the color guide that came with the test strip. Then just balance chlorine/bromine, pH, alkalinity, stabilizer, and any other measures shown on your test strips.

    Foam can damage the hot tub equipment, so it is best to take care of this issue immediately.

    Confused about pH and alkalinity?

    Youre not alone. After all, while they are related and one affects the other, they are also 2 totally different things.

    Does High Ph Cause Hot Tub Foam

    High pH levels can lead to foaming in a hot tub. High pH is considered anything above a pH level of 7.8. But there are a lot of different factors that can cause a hot tub to foam up.

    So, yes is the short answer, but its not the only cause.

    The pH balance is certainly one of them. Cloudy and foamy water indicates that the chemical balance in your hot tub water is imbalanced.

    If your water is cloudy or foamy, its best to also check the pH levels in the water. Use a chemical test kit to check the pH levels.

    Water with a pH level that is greater than 7.8 is too high.

    Additionally, if your waters alkaline levels are higher than 120, it is too alkaline. Either of these issues, high alkalinity or high pH, can cause cloudy water. High pH can also be the cause behind hot tub foam.

    In a recent article, I walk you through all my

    You should add a Calcium Increaser if your calcium hardness level is less than 200 ppm. If your Total Alkalinity level is less than 100 ppm, then you should add an Alkalinity Increaser .

    Finally, to keep your pH level between 7.4 and 7.6 ppm, add pH Up or pH Down.

    Not sure if its safe to use a hot tub if the pH is too high?

    All hot tub chemicals are designed to operate within a range. So its not that you have to hit 1 exact number. But what happens when the pH is too high and is that even safe to use?

    What Causes Excessive Foam In A Hot Tub

    One possible cause of excessive foam in a hot tub is that the water is not properly chlorinated.

    When the chlorine levels are low, it can cause bacteria to grow and produce scum or foam.

    Another potential cause of excessive foam in a hot tub is too much soap or detergent.

    If there is too much soap or detergent in the water, it can form bubbles and result in foaming.

    Finally, another possible reason for excess foam in a hot tub is that the water is over-softened.

    If the water has been softened excessively with salt or chemicals, it can lead to more foaming.

    How To Remove Debris In The Water

    Too Much Hot Tub Foam?

    Make sure your filter is properly working to avoid debris polluting the water. If the filter becomes clogged, you may need to remove the debris by hand to prevent water from becoming foamy.

    Additionally, make sure your hot tubs cover is secured to the hot tub. The cover will eliminate falling leaves and other debris from entering the hot tub when not in use.

    Add An Anti Foam Agent

    If you need a quick fix for your foam issue then adding an antifoam agent or defoamer should do the trick. All you need to do is add a few drops to your hot tub water and the foam should disappear for up to 24 hours. Again, its a good idea to clean your filters after using a defoamer to get rid of as much gunk as possible.

    Bear in mind that using an antifoam agent is really just addressing the symptom rather than the cause and the chances are that the foam problem will return quite quickly. If this is the case then, if you havent done already, go through the steps above to check your water chemistry and sanitizer levels. If this doesnt work, then your best bet is most likely to be to do a full drain clean and refill of your hot tub.

    How Do I Stop My Hot Tub From Foaming

    There are a few things you can do to help reduce the amount of foaming in your hot tub:

    • -Limit the amount of bubble-producing products you use. This includes soaps, shampoos, and bathing oils.
    • -If you must use these products, be sure to completely rinse them off before getting into the hot tub.
    • -Avoid using Dawn dish soap as it is known to produce a lot of foam.
    • -Use affected areas only and avoid scrubbing hard surfaces with a Bristle Brush as this can cause even more foam.
    • -There are commercial defoaming agents available that can be used according to package directions.
    • -Oscillating nozzles can also help to reduce the amount of foam in your hot tub. These can be attached to your existing nozzle and will help to break up the bubbles before they have a chance to form.

    If all else fails, you may need to drain and refill your hot tub with fresh water. This will reset the chemistry levels and should help to reduce the foaming problem.

    Spa Water Balance And Foamy Water

    What’s water balance got to do with it? Nearly everything it seems when pH and Alkalinity are high, and Hardness levels are low, the water becomes “slippery” and fats, oils and dirt combine into soaps. Soap also enters the spa on swimwear, skin or hair and finds it easy to multiply in a high pH, soft water environment.

    Good water balance also allows your sanitizers to work more effectively, reducing contaminants and breaking up oils and scum that can become components of foamy water. Soap scum, or a bathtub ring around the spa is another result of poor water balance.

    Keep A Cleaning Schedule

    Happy Hot Tubs No Foam

    Although you should only have to drain the hot tub every three months or so, this may be more with frequent useand it certainly cant go any longer.

    Make sure you keep your cleaning schedule up to date, or you may have more significant problems than foam to deal with, like hard mineral build-ups and malfunctioning equipment.

    Rule : Test And Balance Hot Tub Water Regularly

    To keep your hot tub water in optimal condition, it is essential to ensure that the sanitizer level in the hot tub water is adequate at all times. Check your hot tub water regularly using a pH level kit. Keep it between 7.2 to 7.8. If the hot tub water has low or high pH levels, it may lead to foaming and other issues.

    If you plan to hold a hot tub party, you need to check and increase the daily sanitizer dose. Toss in a capful of sanitizer per bather after the party. It will maintain adequate sanitizer levels in the hot tub water. If you mess up sanitizer levels in the hot tub, it could also lead to foaming.

    Rule : Hot Tub Only Swimsuits

    To avoid foaming from detergent residue from the clothes, ensure that you do not get into the hot tub with too many clothes on. It does not mean you should insist on a ‘go nude’ policy. Bathers may use swimsuits, but ask them to ensure that it is rinsed well in clean water to wash off any detergent residue from it.

    It is also effective to keep a pair of swimsuits only for hot tub use. This pair should only be rinsed thoroughly in clean water instead of washing with soap. This will avoid the foaming issue to a great extent.

    Why Is Your Hot Tub Foamy

    If your hot tub is foamy, the most likely reason is build-up over time. When people use the hot tub, they still have some residue from shampoo, conditioner, body wash, and laundry detergent.

    None of these things are meant to be used in a hot tub, but theyre unavoidable with general use, so you must clean the hot tub frequently. If you dont, the foam can build up over time and eventually become noticeable.

    Foam in the hot tub can also be due to the pH balance being thrown off. The pH of a hot tub should be between 7.2-7.8 if not kept at this level, the chemical balance in the water wont be right. This is another reason you might see foam, mainly if you havent used the hot tub heavily or cleaned it regularly.

    Rule : Clean The Hot Tub Filters Regularly

    Hot tub filters may not directly help you avoid the foaming issue due to detergents. But filthy filters can aggravate the issue.

    For instance, when the filters are not cleaned regularly, they become less effective in keeping the water clean. It would lead to other serious reasons for foaming, like algal or bacterial growth. So ensure to clean your filters regularly by hosing them down. Deep clean them once a week by submerging them in a water and white vinegar solution to remove residues from the filter pleats.

    Cleaning filters is a must, especially after adding clarifiers to hot tub water to fight the foaming issue. Clarifier helps to clump organic residue in the water, which eventually gets trapped in the filter.

    How To Prevent Foam In Your Hot Tub Naturally

    If you want to save money or use all-natural ingredients, there are some ways to prevent hot tub foam naturally. While these at-home remedies may work to prevent hot tub foam, they should not be used as substitutes for hot tub chemicals. All-natural ingredients are not as powerful as cleaning chemicals designed for hot tubs.

    Aqua Recs offers two quality options: Anti Foam from SpaGuard and Anti Foam from BioGuard.

    If you need to remove foam quickly and you dont have any chemicals on hand, here are a couple of solutions to try:

    • Vinegar/baking soda mixture. Use vinegar and baking soda at a 10:1 ratio. With the average hot tub holding 500 gallons, this means you would need a 5-gallon solution. It would be 90% vinegar and 10% baking soda.
    • Vinegar only. If you dont have any baking soda, you can just use vinegar. Just pour the vinegar directly into the hot tub at a 10:1 ratio. That means for a 500-gallon hot tub, youll need 5 gallons of vinegar. Just be prepared for a strong smell.
    • Drain the water. If youve tried the two solutions above and the foam persists, just drain the water for a fresh start.
