Tunze Eco Chic Refugium Light 8831
The Tunze Eco Chic Refugium Light 8831 is our best-selling refugium light. It is a submersible grow light that fits in almost any refugium, or even in the back chamber of many AIO aquariums. Because the light is submersible, you can get the light much closer to the algae you are growing and avoid light spillage into other chambers, resulting in less nuisance algae in other sump chambers.

Kessil Refugium Lighting
The Kessil H Series lights are grow lights designed for maximum plant and algae growth. When it comes to turbocharging a refugium, there isn’t much better. We also like the Tuna Sun Lights for display refugiums for a more natural look. The optional Gooseneck lets you easily mount the light and position it directly over the algae and the Narrow Reflectors can be used to avoid light spillage.

Brightwell Aquatics Chaeto Gro
One thing you have likely encountered if you have had a refugium is macro algae suddenly crashing and dying. This is often due to a lack of minor elements such as Iron, Manganese, and Molybdenum. Our favorite and bestselling supplement with these elements is Brightwell Aquatics Chaeto Gro. It is a simple, all-in-one supplement with the micronutrients macroalgae need. Any tank growing large amounts of macroalgae can benefit.

Ecosystem Aquarium Miracle Mud
Not all of us want to grow chaeto in our refugium. For Caulerpa or a decorative macroalgae species, having a substrate the algae can root into is beneficial or even necessary. Our best-selling refugium substrate is the classic Ecosystem Aquarium Miracle Mud. The mud contains microelements to promote macroalgae growth, boosting the refugium's effectiveness.

Fiji Cube Hang-On Refugiums
For those who want to add an aquarium but don’t have a sump with a refugium chamber the Fiji Cube Hang-On Refugiums allow you to add a refugium to the back of small to medium-sized tanks. The refugiums include a DC pump for quiet operation and probe and dosing tube holders to keep your display looking clean.
