A CIRCUIT, MADE VISIBLE
Where does the water go?
Trace intake → impeller → foam → upper media → spillway. Lower the lever and watch the amber refiltration loop appear.
Pump view: open teaching section, with slowed rotation and an illustrative axial-in / radial-out path.
MINIMUM / MORE REFILTRATIONMAXIMUM
REFILTRATIONNo added loop illustratedAt minimum, Fluval specifies up to 50%. Intermediate settings and arrow speeds are illustrative.
Clean-media illustration: water moves through the intended media route.
Debris is enlarged for visibility. Brown deposits remain on the upstream face; loading and capture are illustrative.
IncomingReturnRefiltration / bypass
This is a directional teaching animation, not computational fluid dynamics. The raised water level and bypass in the restricted example are qualitative.

Actual delivery depends on media condition and installation. Tank suitability depends on livestock and care, not the nominal capacity alone.
Original, photograph-guided procedural reconstruction. Dimensions and hidden passages remain approximate. Water uses planar reflections and screen-space refraction; light patterns, impeller speed, pores and water traces are illustrative. This is not measured CAD or an assembly/repair guide. The aquarium section is context, not a stocking example. Fluval does not sponsor this exhibit.
