QSB filters offer a simple
solution to the common problem of filter location. They are designed to be
placed directly into your existing sump, trickle filter or raceway tank.
Water injected into the filter's base rises within the main cylinder, fluidizing
the filter media. As the water overflows the open cylinder
top, it quietly returns back down the outside of the filter, into the sump.
simple by design, these filters offer several interesting benefits to the fish
keeper. Aside from a large biological surface area, you also gain a high level
of aeration as the water flows in a thin film down the outside of the filter.
The filter also "bleeds" heat, acting as a cooling tower for the rest
of your system.
