Bubbles may be acceptable if you’re looking to have a relaxing bubble bath, but an excessive amount of bubbles and foam are not acceptable in a hot tub. If you find that patches of foam are constantly floating on the surface of your hot tub water, you may have a problem that needs to be tended to. In this article, we’ll look at what causes hot tub bubbles and what you can do to reduce them to a normal level.
One of the main causes of excessive amounts of foam and bubbles in a hot tub is dirty water. This is nothing to be ashamed of, as it will happen eventually if you use your hot tub at all. The main source of water contamination is the bathers themselves. Bathers can introduce contaminants such as soaps, lotions, cosmetics, deodorants, hair products, body oils, and dirt into the water without even realizing it. Freshly laundered bathing suits can contain soap particles as well. The best way to combat these contaminants is to have bathers shower before getting into the hot tub. It’s also a good idea to rinse freshly washed bathing suits in clean water to make sure they aren’t carrying soap residue.
Low Calcium Hardness Levels
Calcium hardness, or total hardness, is the measure of the amount of calcium and magnesium that’s dissolved in the water. If that total hardness level gets too low, the water becomes soft and the surface tension drops which allows foam and bubbles to form much easier. Low calcium hardness can also cause much bigger problems such as etching and corrosion of the hot tub’s components. If you use a water softener, make sure it’s turned off when you fill up your hot tub. You should measure the total hardness with a water testing kit at least once a week. If you find the levels are too low, you can add a calcium hardness increaser to get them back to the proper standard.
Hot Tub Shocking
Shocking a hot tub doesn’t have anything to do with electricity. In reality, it’s adding chemicals to the water to reduce the number of organic materials that are present. High levels of organics can cause the water to become cloudy, foamy and have a bad smell. You should normally shock the water with a chlorine-based shock when you first fill the hot tub. After that, you can use a non-chlorine-based shock on a weekly or biweekly basis depending on how much use the hot tub is getting.
To keep your hot tub water properly balanced, you’ll have to add chemicals from time to time. If you’re using hot tub chemicals that are old, have been exposed to too much sunlight or they’re just cheap, poor quality chemicals, they might not do the job you need them to do. Make sure to store your chemicals in a cool, dark place. There are many discount brands of chemicals that may cost less upfront, but you’ll likely end up paying more in the long run because of the amounts you need to use to keep your water in balance.
Allowing your hot tub water to breathe will allow for proper oxygen circulation and prevent the water from getting too foamy. If your hot tub hasn’t been getting much use, it’s good to remove the cover every so often to allow the water to be exposed to the air. It’s best if your hot tub can be aired out at least once a week.
