JBJ Rimless Flat Panel aquarium systems bring together simplicity and elegance. Their all-in-one design takes the guesswork out of equipment selection. No added plumbing is necessary and the streamlined design features beautiful, high-clarity glass.  The integrated sump and included filtration media make it easy to start your aquarium!



  • Rimless Design
  • High Clarity Glass & Clear Silicone Seams
  • All-In-One Filtration w/ Built-In Overflow
  • Return Pump(s) with Directional Flare Nozzle


Streamlined Filtration System

The built-in overflow directs water through the activated carbon and ceramic rings to further purify water before it is cycled back into the aquarium. JBJ’s redesigned baffling system maintains a stable water level in the central column that allows a protein skimmer to be used. With all filtration housed in the back of the aquarium and no external plumbing to mess with, all you see is a beautiful viewing window into your aquarium.

Product Questions

Does this product come with a lid or is that sold separately?
Question by: Nicholas C on Nov 19, 2023, 3:38 PM
Hi there, thank you for the question. This tank will not include a lid, that would have to be purchased separately.

Can you recommend a light for this tank was thinking of the kessil a160
Question by: Peter massaro on Jun 29, 2022, 12:46 PM
That is a great question. Any one of the lights below would work well for that aquarium for a mixed reef. The A160 may be too powerful for that aquarium unless turned way down.

Answer by: Matt Lucero (BRS Staff) on Jan 17, 2022, 1:48 PM
Hey guys! Just wondering what you guy would recommend for the filter media on this tank. I plan on setting it up as a heavily planted freshwater tank but not sure how to set up the filter. Thank you.

Jon Wilgus
Question by: Jonathan Wilgus on Dec 26, 2021, 7:39 PM
Hello Jon,

Thank you for the question. This tank comes with a Media Starter Pack that includes (Coarse Sponge, Ceramic Rings, Activated Carbon). You can take out the sponge and rinse it once a week, and replace the Activated Carbon every two to 4 weeks. - The Ceramic Rings are use for Biological Filtration so you don't want to fully rinse them after your tank is cycle, this is where the beneficial bacteria will be hosted.

You can replace/upgrade the carbon with sine Chemi-Pure Elite - Boyd Enterprises.
