When it comes to replacing a filtration system for a float tank, there's sadly no easy answer. There isn't a one-stop shop place to get replacement parts for float tanks (yet). Most systems are piecemealed together by manufacturers to work specifically for their systems.

In addition to all that, they also often use internal customized materials to accommodate the specific needs of float tank solution. So without some serious internal knowledge of how those systems work, it's nearly impossible to safely and accurately just swap out one piece for another.
