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 two 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 holders (hold 2 filter socks) - need acrylic glue to put sock holder up
  • 2 x filter sock silencers
  • 2 x filter socks (200 micron)
  • 1x fixed height baffle slot (1st slot)
  • 1x water height adjustable baffle slot (2nd slot)

Hey There, unfortunately I do not have these exact dimensions. I would recommend reaching out to Fiji cube directly!

Will this product fit this tank? "Aqueon Standard Glass Aquarium Tank 29 Gallon" The dimensions given in a previous question were not matching the tank description and specs on Petco's website.
Question by: Joe on Jul 1, 2022, 8:38 PM
Thanks for the question! This baffle kit will work on the Petco tank, the Petco Specs include the rim in their dimensions on top of the glass dimensions mentioned in the last question.

Do these baffles (29gallon setup) work for a standard 20 gallon tank, too? Also, what are the dimension of these baffles? Thank you

Thank you for your question, for a standard 20 gallon tank you would need the "20 Gallon Long Sump Baffle Kit - Fiji Cube" SKU 213952. Happy Reefing.
