The Fiji Cube Sump Baffle Kit is the premier option for creating a custom, economical sump for your reef without the high cost typically associated with having one fabricated for you. These Baffle kits are made to fit a number of common aquarium sizes and include all of the necessary components to create partitions in the aquarium. The 20, 29, and 40 gallon kits include filter sock trays and baffles to support a skimmer compartment, refugium, and return pump, and the return pump baffles include trays for media and/or bubble trap foam. All that’s needed aside from the kit is an appropriately sized aquarium and the silicone sealant. 


The Sump Baffle Kit uses strong, quality parts throughout. After securing the baffles in place, just apply aquarium silicone to the joints between the baffles and the aquarium, allow for curing time, and you’re ready to go! 



  • Integrated filter sock holders that can hold three 4” filter bags
  • Filter sock silencers to lower noise caused by the water flow that goes into the filter socks
  • Baffle slots that allow customization of spaces for protein skimmer, media reactor, refugium and other equipment
  • Adjustable water level (8" to 15") to meet your protein skimmer water height requirement
  • 2 Media trays to hold bio-foams and/or media
  • Cast acrylic
  • Silicone ready


What’s Included?

  • 1 x filter sock holder (holds 3 filter socks) - need acrylic glue to put sock holder up
  • 3 x filter sock silencers
  • 3 x filter socks (200 micron)
  • 1x fixed height baffle slot (1st slot)
  • 1x water height adjustable baffle slot (2nd slot)
  • 2x bio-foams
  • 2x media trays (to hold foams or filter media)
  • 1x bubble trap baffle slot (3rd slot)

Is it possible to take out the filter socks and run a filter roller or is it designed specifically to run the socks?
Question by: Collin Nelson on Dec 4, 2023, 3:12 PM
Hey there, thanks for the question. You could use a filter roller with the baffle kit, you would just need to remove the filter sock holder and make some modifications.
