The JBJ 4 LED NANO-GLO was specifically designed for the 28G Nano Cube aquariums, which is sold with a transparent filter basket. In-Tank Refugium

This 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.




Refugiums 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 stabilize 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 lumen each while only consuming 1 watt per bulb. The new higher output design still creates minimal heat and lasts an amazing 40,000 hours.

Nano Glo 2Suction cup Rear Mounted

The NANO-GLO securely attaches to the rear wall of the aquarium via an integrated suction in the light housing and a suction cup that is placed inside the filter chamber. This compact design (3/4” width) discreetly is hidden and is placed out of the way of routine maintenance and cleaning. The inside the aquarium will instantly float towards the surface when the light is removed preventing it from sinking to the bottom of the tank.

Filter Basket Layout

First Chamber – Place a small ball of Chaetomorpha algae which should fill up half the chamber. This will provide room for growth.

Second Chamber – Place the activated carbon bag to help remove dissolved organic compounds. Replace monthly as odor and discoloration of the water can occur.

Third Chamber – Place the mechanical sponge to prevent any loose strands of the Chaetomorpha algae (spaghetti algae) from entering the pump column. This will also help trap particulate matter and free floating debris.


Nano Glo Light For 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.
