Float Tank water Quality
The float tank uses a UV sanitation system and swimming pool filter as well as hydrogen peroxide to maintain the quality of the water.
The water is pumped through the filter and the UV sanitizer. Both the pool filter and sanitizer are over sized for the relatively small tank and quantity of water. They are both designed for a swimming pool. But, the larger capacity combined with a powerful pump and 1-1/2 inch PVC plumbing allows the water to be turned over many times in a short period of time. The pump is run after each client as well as longer runs at the beginning and end of the day and when time permits.
A UV sanitizer kills 99.99% of all microorganisms that pass through it. This include bacteria, virus and all types of fungi and protozoa. It does this using ultraviolet light emitted from special UV bulbs. Our sanitizer is a larger high volume device, originally intended for swimming pools, that can sanitize a large volume of water quickly.
Our tank water is treated with hydrogen peroxide. The hydrogen peroxide that we use is pharmaceutical grade and industrial strength hydrogen peroxide at a concentration of 35%. We check the concentration in the tank at least twice a day and maintain it at 100 parts per million. 100 ppm is on the high side for tank sanitation but not high enough to cause any kind of irritation or other problems. 40 ppm is recommended to keep the water clean. Hydrogen peroxide acts as both a sanitizer and as an oxidizer. It kills any microbiological organism that it comes in contact with. As an oxidizer it breaks down any organic material that it comes in contact with, somewhat like the way a flame would in a dry environment. Any dead skin cells, oils etc. are chemically destroyed by the hydrogen peroxide and any particulate matter in the water is trapped by the filter. Hydrogen peroxide leaves no toxic residue in the water as it's decomposition products are oxygen and water. The UV sanitizer further potentates the effect of the hydrogen peroxide. As it passes through the UV light it's oxidative potential is multiplied.
At regular intervals the tank is also cleaned by hand. A spa employee enters the tank and wipes the walls above the water line with a 3% solution of hydrogen peroxide and also wipes the surfaces below the water line.
The methods that we use to maintain the quality of our water are accepted as standard in the float tank industry and almost all float tanks are maintained using these same sanitation methods. Chlorine and bromine, such as are used in swimming pools and hot tubs, are not recommended for use in float tanks. Magnesium sulfate, of which there is over a thousand pounds of in the tank, is antimicrobial, making it a difficult environment for bacteria to propagate in even if the other sanitation measures were not in place.
