The CPR Aquatic AquaFuge2 Hang-On Refugium is a user-friendly, plug-and-play hang-on module that excels for aquariums without a sump or for hobbyists who want quick installation and low fuss. While it can be more expensive per liter of refugium volume than in-sump options like the Fiji baffle kit or Eshopps cube, its ease of setup and compact footprint deliver strong practical value for small-system refugium needs. In a refugium modules lineup it’s the convenient, tank-side solution for hobbyists who need refugium function without sump modifications.
