ZS Series Sumps

ZeroEdge ZS Classic Refugium incorporates a split design. The left side is for use with a protein skimmer and the right side is for the refugium. Keeping these two different styles of filtration separate, allows them both to work properly.

Classic Refugium Sumps include the following:

  •  1/4” and 3/8” robust high quality cast materials.
  • CNC fabricated parts.
  • Solid tops with cutouts allowing for the use of lids to seal in moisture, prevent splashing and provide soundproofing.
  • Adjustable weir plate for water height preference on skimmer side.
  • Sock holders
  • Probe holders for added convenience.
