MT-408L by Jbj aquariums is an all glass fish tank with hood and filter.

JBJ 12G Nano Cube is the original all-in-one aquarium that has made reef keeping easy. All models come standard with 8 high powered 1.3 watt LEDs, 2 built-in cooling fans to dissipate excess heat, new highly efficient drivers, 3 stage filtration, and return nozzle for directional flow output. An optional cabinet stand is also available.


12 Gallon Glass Cube offers panoramic viewing with smooth rounded corners. Provides the ideal dimensions for a mini-reef tank that requires depth for proper rock stacking.


Built-in 3 Stage Filtration
The Nano-Cube filtration system allows for better surface skimming and more room in the rear for larger pumps for DIY customers. The filtration compartment is hidden in the rear and provides maximum space for tank inhabitants. All models now include a output return nozzle for directional flow control.

Includes 8 high powered 1.3 watt LEDs. A combination of 3-10K and 5-20K the light output is optimal for coral growth. Utilizing primary and secondary optics and a combination of 10K and 20K LEDs gives an even spread and optimum Kelvin for your marine live. Installed with splash guard lens.

Fan-Cooled “Flip Top” Canopy
Our new redesigned canopy offers (2) built-in 60x60mm cooling fans that deliver the proper CFM output for heat removal while being very quiet. Both fans automatically turn on with the lighting. Fans are protected with a separate splash guard to resist corrosion and salt creep. Our heavy duty ABS canopy easily flips back and can be held in place for routine maintenance. The front of the canopy offers a feeding door that also flips back for quick access.
