FiltrationHardware Specification
Hang-On-Back Filter (HOB)
A classic, beginner-friendly filter that hangs on the back glass of the tank. It draws water up a tube, filters it through vertical cartridges, and returns it over a waterfall lip, oxygenating the surface.
Primary Biological & Physical Purpose
Provides highly convenient mechanical, chemical, and biological filtration for small-to-medium aquariums.
Operational Mechanics & Physics
An internal impeller pump pulls water up, forces it through a cartridge containing floss and carbon, and flows it back over a spillway.
Maintenance & Longevity Protocol
Rinse the cartridge in tank water monthly, or replace the mechanical floss block. Keep bio-sponges in the chamber untouched to preserve bacteria.
