PhosBan reactors are designed on the updraft principle to achieve the best efficiency when using PhosBan or other filtration chemical. By pushing water from bottom to top through a diffusion plate. This constrains a homogeneous distribution of water through the filtration media and prevents preferential circuits. It is possible to install it in suspension at the back of the aquarium or to place it under the aquarium.
Ideal for GFO (phosphate absorbent resin) use.
