Ashkahn and Graham break down the differences between float tanks designed for home use in comparison to ones intended for a commercial setting. Depending on how it's intended to be used can drastically affect the construction of the tank. Most home use tanks, for example, aren't made of fiberglass, because those large, rigid structures are difficult to move by yourself or just with one other person. Likewise, the filtration demands for a home use tank are a lot different.
Listen in and check out all the differences and which tanks are more intended for use at home as opposed to commercial use.
