Sorry to disagree but a recirculation polishing system will not remove tank wall accumulated debris. It will only remove debris that is in 'suspension' in the fluid/oil.
A recirculation system will tend to keep the particles from adhering to walls as it removes them quickly upon their formation (as agglomerates of hard had 'soft' particles).
Dont waste time and money with a recirculation polishing system without FIRST mechanically cleaning the tank.
