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 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.
