Many float spas have a water ecology that I am not happy about. The more aerobic (homeostasis) the water is the more I get out of my session. Sure, they soften your skin and make you feel good but most spas that I have been into are hydro-phobic. The water is unstructured and I have to bring my own tools in my back pack to structure the water before I go in for my float session. I am not concerned with the puritiy of the water. That is not the issue here. It is that I need the water to become hydro-philic first. I don't care how clean it is. Even if the water is structured then I have the salt to deal with. I only add a tablespoon of infused epson salt. You don't need that much. Just a little can make the tub charge a night and day difference. You can go to Radio Shack and get a 20 dollar meter if you want to test it yourself. There are waterproof pens that I place in the bottom of the float spa that are filled up with diamond dust and other minerals that are sealed in the welded pen, looks like an ordinary pen.
These sell for about 50 to 200 dollars each. I have the ones that structure the water the most and would love for
someone to do a video with it in their float session. If you wand the salt, the salty tastes changes a night and day difference. I will send a sample to anyone that calls and agrees to do a simple 2 minute video on your phone and upload it to youtube.
