This is a custom air circulation fan and system I developed for the Samadhi tanks, but it can be used with any tank that has 1 1/2 inch openings in the back, such as the escape pod tank.
If air circulation within your tank is a new concept for you, then you have not been floating in a truly healthy tank, as tanks without air circulation usually get steamy and stuffy. This concept is not new, but for some reason only a small handful of float manufacturers have developed air systems for their tanks. Float lab tanks in LA has small amounts of air added to them (oxygen tanks), Escape pod tanks had a fan system that came with their tanks, and Aqua Anima in Sweden has an air system.
