Every now and then, people ask if we change the water in the pods between each user and, they get surprised when the answer is "no". That said, the water in the Float Tank will likely be some of the cleanest water you've ever entered. Here is how:
The Float Tank Association (yes - it exists!) has created the US Float Tank Standards - a stringent set of regulations regarding sanitation, cleaning, and maintenance. They state the water should be changed every 1000 floats or every 6 months.
Public swimming pools and hot tubs are used by many at once and the health department regulations state that all the water must be filtered once every 6 hours. Our Pods are designed to filter the water on the hour 24/7 when the pod is not in use, as well as before and after each use. In fact, the water cycles through our Sanitation System (read below) 3-5 times each filtering cycle.
Additionally, each Pod contains about 700 pounds of magnesium sulfate (Epsom & Dead Sea salt) which is a natural antimicrobial. In reality, the salt content in the tank is so high that bacteria and fungi can't survive in it. Researchers have actually injected bacteria into such salt concentration and it died very quickly. Just remember that our salt concentration is almost 3 times greater than that of the Dead Sea, which is roughly 8.6 times saltier than the ocean. This salinity makes for a very harsh environment in which nothing can flourish in it (hence its name). Hence, the Salt concentration is a natural antibiotic, antiseptic and antimicrobial agent as well.
Surely that's enough to cover our bases, right? Probably true, but the float tank industry is committed to the highest standard of cleanliness and our tank often exceed the requirements of the health departments, so there's more…
As humans, we're able to tolerate the UV rays of the sun. Bacteria, viruses, and molds aren't that fortunate.
UV works to purify by damaging cellular DNA—when anything undesirable in the pod meets these purifying rays, they are killed. UV treatment protects against viruses (including Hepatitis, which is resistant to chlorine), molds and bacteria.
Ozone Purification System:
You know that clean fresh smell in the air after a summer thunderstorm? We can thank Ozone for that! It's (O3) comprised of 3 oxygen atoms, however, it's unstable like this, thus causing a release of one of the atoms. When this extra oxygen comes in contact with anything undesirable in the water, it's almost immediately oxidized and, thus, purified. Ozone kills bacteria 3,000 times faster than chlorine and has 50 times the power. It eliminates organic material and viruses in addition to bacteria, mold, and yeast.
Despite all these various stages of cleanliness, sanitation and protection…Don't forget that each user is mandated to shower before entering the tank even if they showered at home.
