The bubbles don’t harm you or the hot tub at any time and are all ubiquitous household items, many of which can be found in our people at any given time, so it makes sense only to see bubbles in the hot tub.
Another potential cause of foaming is the accumulation of bacteria, also known as biofilms. If the product is not thoroughly rinsed after cleaning the filter, it also can cause foaming.
If you don’t regularly flush the filter or use monthly deep cleaning like Filter Restore to clean the filter, the filter can be a source of foaming if you have enough surfactants in your water to cause foaming. If the water is almost ready to be replaced and starts to foam, the best thing to do is flush and clean the hot tub.
A defoamer for hot tub water will help combat foam for a while, but it’s best to be as clean as possible before entering the tub. Then, balance the water chemistry and change the water every three months to remove the foam. Scheduled water and filter changes and weekly water chemistry monitoring are the best way to avoid foam in the hot tub.
Because a hot tub works differently than a bathtub, foam in spa water indicates a problem and can cause more problems if foam gets into pipes and pumps. Foam in a spa is due to the water being “full” or “old,” and activating spa jets when water is such causes foam to appear on the water’s surface. Typically, foam in a hot tub can be caused by excessive lotions, dirt, perfume and deodorants that people have gotten into the water.
Low calcium levels (water hardness) in the spa can reduce the surface tension of the spa water and lead to excessive foaming. In addition, low calcium levels (water hardness) can reduce the surface tension of the spa water and lead to excessive foaming of the water.
The oils in water can come from body care products such as lotions, sunscreens and deodorants, hair care products like conditioner and mousse can also be problematic; too much or the wrong amount of chemicals in the water can also contribute to causing foam in your spa.
When these impurities are in the water, they stick to the bubbles, making the water too thick and foaming if it is not treated further (usually during the day ). Therefore, another tip that we recommend is to purchase a chemical defoamer, as this is ideal if you are short on time and cannot purify the water.
Check the level of chemicals and disinfectants in your water if necessary and add more if required to restore the correct level. Before taking any corrective action, test your water to see your pH, alkalinity, and disinfectant and check your total dissolved solids (TDS) – these are surfactants.
If the water is at the wrong pH and is too acidic or alkaline, it can cause many problems, including excessive foaming. Cloudy or foamy water often indicates an incorrect chemical balance in thermal water. A ring around the tub around the spa can also result from poor water balance. Cloudy, frothy water occurs when soaps, shampoos and lotions fly off people’s skin or swimwear when they take a bath.
To rid your water of these unwanted guests, shock your spa every big party and regularly at least once a week. Pouring more chlorine into the spa will help destroy everything that makes your spa frothy (no matter if the chemical levels are balanced, but the whirlpool remains frothy).
Take your filters and wash them thoroughly or soak in a filter cleaner overnight. Swimsuit residue from laundry detergent can form a foamy mass, so make sure your swimwear is clean and rinsed with fresh water before getting into it.
All you need at a Sundance Spa to keep your water clean is a small amount of powder disinfectant and a minimum amount of chlorine-free spa shock. If you regularly do your hot tub chemistry, spa water is thoroughly mixed with disinfectant chemicals and calcium to neutralize surfactants and prevent bubbles from forming. However, the first two methods involve maintaining the water, and you will still feel foam and cloudy water build up in the hot tub.
