Swim spas and Epsom salts have a lot in common as far as health benefits are concerned, but can you actually use them together? The short answer is no. Unfortunately, the same qualities that make Epsom salts so sought after, make them extremely unsuitable for use in your spa pool.
Here's everything you need to know about Epsom salts and how they can affect your swim spa:
High salt or mineral levels can damage your spa pool. For Epsom salt to be effective, you need to achieve a 2% concentration. That’s about 20,000 parts Epsom salt per million of water (PPM). The problem is that most spas are only designed to handle salt levels of around 1500 PPM. Anything above that can corrode and damage important metallic parts, like the heater and pump.
You could potentially avoid corrosion and damage if you drained your swim spa after each Epsom salt bath, but would you really want to waste hundreds of liters of water just for a quick soak? Draining your swim spa more often than necessary can also shorten its lifespan, and so, for this reason, it’s better to use your Epsom salts in bathtubs or foot baths, where you can regularly drain the water.
Salt water can also damage unsealed concrete and similar surfaces. Minerals can seep through the concrete and crystalize between the surface’s crevices. This can lead to cracks, so make sure to wash away any spillage with water.
Epsom salts are said to have a myriad of health benefits, but they’ll do more harm than good to your spa pool. Its chemical components can corrode metal parts and possibly damage your swim spa’s filters, pumps, and heater. Use Epsom salts in your bathtub or foot bath, but skip the swim spa if you want to avoid costly repairs.
