It’s indisputable that Epsom salt and hot tubs are the flawless combination for general relaxation and pain solace for joints and muscles. This is one of the reasons why most people are tempted to use Epsom salt in a hot tub.
Irrespective of the numerous benefits of Epsom salt, it should not be used in a hot tub. This is because it can ruin a hot tub or subject you to extreme injuries.
Will Epsom salt ruin a hot tub?
The answer is Yes. The effects of using Epsom salt in spas are detrimental, and thus the need to avoid it all cost. There are several safety concerns that you need to be aware of before adding Epsom salt in your hot tub.
So, let’s look at some of the reasons why Epsom salt can ruin your hot tub.
Refined Epsom salt, also known as Magnesium Sulfate, is an alkaline compound. The compound comprises of mildly acidic properties that can distort the PH level of the water contained in your Jacuzzi.
The disparity in hot tub water can induce other issues, such as a decline in the performance of the hot tub sanitizer and corrosion of the spa’s equipment.
Chlorine is one of the most used chemicals in a Jacuzzi. At no time should chlorine and magnesium be mixed, since the reaction between the two compounds can prompt flash burns.
Most people who have added Epsom salt to their Jacuzzi, have ended up nursing serious injuries resulting from flash burns. Keep in mind not to add Epsom salt to your hot tub as it will cause a disparity in PH balance, thereby ruining your spas.
It Intensifies the Entire Dissolved Solids
Epsom salt is used more often in regular bathtubs. To apply it in a bathtub, you only need to add approximately 2 cups of Epsom salt to enjoy its therapeutic effects entirely.
The standard capacity for a bathtub is 80 gallons of water, while the average capacity for a hot tub ranges from 400-500 gallons of water. To realize a similar concentration in the hot tub, you should add at least 10-12 cups of Epsom salt, which is too many solids.
Bathtubs are relatively easy to drain and are often drained. Unluckily, hot tubs are not easy to drain nor drained as often as bathtubs.
In order to impede scale buildup in the surfaces and equipment of the hot tub, the hot tubs manufacture recommends homeowners to only drain spas when the level of the entire dissolved solids hit 1,500 ppm.
Neglecting to do so can invalidate your warranty.
If you do use Epsom salt in a hot tub, then you’ve to add 10-12 cups, which can escalate the entire dissolved salts, surpassing the permitted threshold of 1,500 ppm. Even though the Jacuzzi heaters are more vulnerable to the scale build-up, other components of the Jacuzzi, such as pool pumps, water lines, and jets can also buildup scale if you neglect to maintain a perfect water balance.
Note that it is possible to use Epsom salt in a plain water hot tub as long as you’re prepared to drain it more often.
The absence of chlorine in the plain water means there will be no injuries resulting from Epsom salt. To avoid corrosion to the Jacuzzi equipment, only add the amount of Epsom salt stipulated by the manufacturer.
