📖 Overview
A sump moves all life support below the display tank. Water overflows through a drainbox into the sump, where it flows through filtration stages before being pumped back up. Sumps allow massive filtration, hide equipment, add water volume for stability, and provide a refugium for macroalgae and pod culturing.
