JBJ Nano-Glo 4-LED Refugium Light



JBJ Nano-Glo 4-LED Refugium Light


JBJ introduces the NANO-GLO LED to upgrade your existing Nano Cube into an “In-Tank” Refugium. The NANO-GLO LED refugium light boasts 4 powerful high intensity LED’s that evenly distribute light for macro algae, and aid in the removal of unwanted phosphates and nitrates. Its innovative design utilizes a powerful suction cup to attach to the rear wall of the aquarium for mobility and secure placement.


In-Tank Refugium
The NANO-GLO was specifically designed for the 28g Nano Cube CF QUAD aquarium, which is sold with a transparent filter basket. But the design is so versatile that it can be used to light any small nano aquarium that usually cannot accommodate top lighting due to space constraints and fully enclosed canopies.


Refugium Benefits
Refugiums provide natural filtration as algae grows in a controlled area with light and water flow to export unwanted nutrients such as phosphates and nitrates. They also help stabalize the pH and oxygen levels consistently throughout the day by absorbing CO2 gas during evening hours when the main tank lights are off. And they are the perfect way to grow natural food sources that propagate and feed the aquarium naturally.


High-Intensity LEDs
These small LED’s produce an incredible 70 lumens each while only consuming 1 watt per bulb. The new higher output design still creates minimal heat and lasts an amazing 40,000 hours.

Suctio Cup Rear Mounted
The NANO-GLO securely attaches to the rear wall of the aquarium via a suction cup. The suction cup has a lever to squeeze all the air out to make sure that the suction cup will stay in place.


Lighting the Refugium
Since pH and oxygen levels generally drop once the main tank lights are turned off, we suggest running the NANO-GLO on a reverse daylight cycle. This simply means to have a timer turn on the NANO-GLO LEDs once the main tank lights are turned off. The NANO-GLO should be turned off prior to the main tank lights turning on again.
